Answers

Answer:

  center left-turn lane

Explanation:

A center left turn lane will be marked as described. The arrows, if present, generally indicate that left turns are permitted from the lane with these markings.

__

Question 6: Which of the following is NOT true if you are changing into a
turning lane?
You should activate your signals 100 feet beforehand
You should activate your signals when you get into the turn lane
You should activate your signals before you get into the turn lane
You should use your hands to signal if your lights do not work

Answers

Answer:

You should activate your signals 100 feet before you turn, becuase of that you should not wait until you are turning to turn on your signals. If you do not have working lights use your hands. So the answer that is inccorect is B.

You should activate your signals when you get into the turn lane is NOT true

Because you are supposed to single beforhand not while you're in the lane.

Steam enters an adiabatic turbine at 8 MPa and 500 C with a mass flow rate of 3 kg/s andleaves at 30 kPa.The isentropic efficiency of the turbine is 0.90. Neglecting the kinetic energy change of the steam, determine (a) the tem-perature at the turbine exit and (b) the power output of theturbine

Answers

Answer:

(a) The exit temperature = 69.1°C

(b)  The power output = 8.3 MW

Explanation:

(a) The enthalpy of steam at 8 MPa and 500°C is given (from online sources) as h₁ = 3399 kJ/kg

The exit temperature = The saturation temperature at 30 kPa = T₄ = 69.096 + 273.15 = 342.246 K

The exit temperature = 69.1°C

(b) The mass flow rate = 3 kg/s

The isentropic efficiency = 0.9 = (h₁ - h₂)/(h₁ - h₂[tex]_s[/tex])

s₁ = 6.727 kJ/kgK

h₂[tex]_s[/tex] = 289.229+ 2335.32* (6.8235 - 6.727 )/6.8235 = 322.26 kJ/kg

Therefore, h₂ = h₁ - (h₁ - h₂[tex]_s[/tex])*0.9

h₂ = 3399  - (3399  - 322.26 )*0.9 = 629.934 kJ/kg

The power output = [tex]\dot m[/tex](h₁ - h₂) = 3 *(3399 - 629.934) = 8307.2 kJ/s =

8.3 MW.

The next day, you plan to hike the mountain trail and return to camp before dusk. Your friends suggest that after hiking, you might want to enjoy a warm shower. They suggest that before you head out in the morning, you should suspend a strong, black cloth bag full of about 5 gallons of water, so that it sits in sunshine all day. When you return, the water should be warm, and you can enjoy a luxury because of good planning. It works and you are delighted and refreshed! The process that you used to get a warm shower illustrates
