An automotive fuel cell consumes fuel at a rate of 28m3/h and delivers 80kW of power to the wheels. If the hydrogen fuel has a heating value of 141,790 kJ/kg and a density of 0.0899 kg/m3, determine the efficiency of this fuel cell.

Answers

Answer:

The efficiency of this fuel cell is 80.69 percent.

Explanation:

From Physics we define the efficiency of the automotive fuel cell ([tex]\eta[/tex]), dimensionless, as:

[tex]\eta = \frac{\dot W_{out}}{\dot W_{in}}[/tex] (Eq. 1)

Where:

[tex]\dot W_{in}[/tex] - Maximum power possible from hydrogen flow, measured in kilowatts.

[tex]\dot W_{out}[/tex] - Output power of the automotive fuel cell, measured in kilowatts.

The maximum power possible from hydrogen flow is:

[tex]\dot W_{in} = \dot V\cdot \rho \cdot L_{c}[/tex] (Eq. 2)

Where:

[tex]\dot V[/tex] - Volume flow rate, measured in cubic meters per second.

[tex]\rho[/tex] - Density of hydrogen, measured in kilograms per cubic meter.

[tex]L_{c}[/tex] - Heating value of hydrogen, measured in kilojoules per kilogram.

If we know that [tex]\dot V = \frac{28}{3600}\,\frac{m^{3}}{s}[/tex], [tex]\rho = 0.0899\,\frac{kg}{m^{3}}[/tex], [tex]L_{c} = 141790\,\frac{kJ}{kg}[/tex] and [tex]\dot W_{out} = 80\,kW[/tex], then the efficiency of this fuel cell is:

(Eq. 1)

[tex]\dot W_{in} = \left(\frac{28}{3600}\,\frac{m^{3}}{s}\right)\cdot \left(0.0899\,\frac{kg}{m^{3}} \right)\cdot \left(141790\,\frac{kJ}{kg} \right)[/tex]

[tex]\dot W_{in} = 99.143\,kW[/tex]

(Eq. 2)

[tex]\eta = \frac{80\,kW}{99.143\,kW}[/tex]

[tex]\eta = 0.807[/tex]

The efficiency of this fuel cell is 80.69 percent.

A refrigeration system was checked for leaks. The system temperature and surroundings were 75°F when the system was charged with nitrogen to 100 psig. The temperature then dropped to 50°F. What should the pressure be if no nitrogen has escaped?
A) 9 psig
B) 94 psig
C) 100 psig
D) 90 psig

Answers

B 94 psig because the temperature dropped too

The temperature and pressure of an ideal gas are directly proportional

The pressure of the system should be in the range B) 94 psig

The given refrigerator parameters are;

The temperature of the system and the surrounding, T₁ = 75 °F = 237.0389 K

The pressure to which the system was charged with nitrogen, P₁ = 100 psig

The temperature to which the system dropped, T₂ = 50 °F = 283.15 K

The required parameter;

The pressure, P₂, of the system at 50°F

Method:

The relationship between pressure and temperature is given by Gay-Lussac's law as follows;

At constant volume, the pressure of a given mass of gas is directly proportional to its temperature in Kelvin

Mathematically, we have;

[tex]\dfrac{P_1}{T_1} = \mathbf{\dfrac{P_2}{T_2}}[/tex]

Plugging in the values of the variables gives;

[tex]\mathbf{\dfrac{100 \ psig}{297.0389}} = \dfrac{P_2}{283.15}[/tex]

Therefore;

[tex]P_2 = \mathbf{283.15 \, ^{\circ}F \times \dfrac{100 \ psig}{297.0389\ ^{\circ}F} \approx 95.3 \, ^{\circ}F}[/tex]

The closest option to the above pressure is option B) 94 psig

Answer:

Education and training I did the TEST and got it right.

Of the core elements of successful safety and health programs, the other one aside the given two that relates to individual roles is;

Education and Training Program.

According to OSHA(Occupational Safety and Health Administration), there are 7 core elements of an effective safety and health program.

These 7 core elements are namely;

1) Management Leadership.

2) Worker Participation.

3) Hazard Identification & Assessment.

4) Hazard Prevention & Control.

5) Education & Training Program.

6) Evaluation & Improvement.

7) Management of Contractors / Staffed Employees.

Now, we have been given 2 of the 7 which are Management leadership and

worker participation. However, we are told to find another one that relates

to individual roles. The only other one that is individual specific is Education

and Training program because it is the responsibility of every staff from top

to bottom to know all about safety.

Taking what you have learned about Ohm's law what would the current be through a circuit if the power supply was 110 v and the total resistance on the circuit was found to be 15.2 kiloOhms?

Answers

Answer:

7.24 mA

Explanation:

Ohm's law states that the current passing through two points is directly proportional to the voltage across the two points.

V ∝ I

V = IR

R is the resistance which is the constant of proportionality, V is the voltage and I is the current.

Given that V = 110 V, R = 15.2 kΩ

Therefore using ohms law, we calculate the current as:

[tex]V=IR\\\\I=\frac{V}{R}\\\\I=\frac{110}{15.2*10^3}\\\\I=7.24*10^{-3}\\\\I=7.24\ mA[/tex]

Answers

Answer:

15300 N

Explanation:

[tex]\rho_i[/tex] = Density of air at inlet

[tex]\dfrac{m}{t}[/tex] = Mass flow rate = 60 kg/s

[tex]v_i[/tex] = Inlet velocity = 225 m/s

[tex]\rho_o[/tex] = Density of gas at outlet = [tex]0.25\ \text{kg/m}^3[/tex]

[tex]A_i[/tex] = Inlet area

[tex]A_o[/tex] = Outlet area = [tex]0.5\ \text{m}^2[/tex]

Since mass flow rate is the same in the inlet and outlet we have

[tex]\rho_iv_iA_i=\rho_ov_oA_o\\\Rightarrow v_o=\dfrac{\dfrac{m}{t}}{\rho_oA_o}\\\Rightarrow v_o=\dfrac{60}{0.25\times 0.5}\\\Rightarrow v_o=480\ \text{m/s}[/tex]

Thrust is given by

[tex]F=\dfrac{m}{t}(v_o-v_i)\\\Rightarrow F=60\times (480-225)\\\Rightarrow F=15300\ \text{N}[/tex]

The thrust generated is 15300 N.

CAD(computer-aided design) software and is used in__________and __________that show how to construct an object. Technical drawings show in detail how the pieces of something relate to each other.

Answers

Answer:

Plans; blueprints.

Explanation:

In Engineering, it is a common and standard practice to use drawings and models in the design and development of various tools or systems that are being used for proffering solutions to specific problems in different fields such as engineering, medicine, telecommunications and industries.

Hence, a design engineer make use of drawings such as pictorial drawings, sketches, or technical drawing to communicate ideas about a design to others, to record and retain informations (ideas) so that they're not forgotten and to analyze how different components of a design work together.

Technical drawing is mainly implemented with CAD (computer-aided design) software and is typically used in plans and blueprints that show how to construct an object.

Additionally, technical drawings show in detail how the pieces of something (object) relate to each other, as well as accurately illustrating the actual (true) shape and size of an object in the design and development process.

2. How many photocopies are required to earn $ 500 profit?

3. Identify the safety margin at breakeven point.

Answers

Answer:

1) 739 copies (739.7260273972603).

2) 5000 copies.

Explanation:

27000/365 = 73.97260273972603 (Their daily wins). How much times $.10 is equal to 73.97260273972603?

I used a two step equation to get it.

0.10 * x = 73.97260273972603/0.10     = /0.10         x = 739.7260273972603

They need to sell 739.7260273972603 copies a day to get 27000$ a year.

an equation (y = mx+b) can be

y = 739.7260273972603x

To earn a 500$ profit we need to do the same two-step equation but instead of 73.97260273972603 use 500.

0.10 * x = 500/0.10     = /0.10         x = 5000

5000 copies needs to be sold to get a 500$ profit.
