Im not really sure tbh
Explanation: Water at 15°C is heated by passing it through 2-cm internal-diameter thin-walled copper tubes. Heat is supplied to the water by steam that condenses outside the copper tubes at 120°C. If water is to be heated to 65°C at a rate of 0.2 kg/s, determine (a) the length of the copper tube that needs to be used and (b) the pumping power requirement to overcome pressure losses. Assuming the entire copper tube to be at steam temperature of 120°C
2)Prueba de presión Cuando a una persona se le somete a una prueba de presión, por lo general se le indica que, al llegar el ritmo cardíaco a cierto punto, la prueba deberá detenerse. El máximo ritmo cardíaco permitido, m, en latidos por minuto, puede ser aproximado por la ecuación: m= - 0.875 x + 190 donde x representa la edad del paciente de 1 a 99. Usando este modelo matemático determinar: a) El ritmo cardiaco máximo para una persona de 50 años. b) La edad de una persona cuyo máximo ritmo cardiaco sea de 160 latidos por minuto.
Usando la ecuación de regresión que modela la frecuencia cardíaca máxima, podemos obtener el valor predicho de los problemas dados así:
La ecuación lineal que modela la frecuencia cardíaca máxima permitida en función de la edad del paciente está relacionada con la fórmula:
m = - 0,875x + 190x = edad del paciente; m = máx. frecuencia cardíaca permitida
1.) Frecuencia cardíaca máxima permitida para una persona de 50 años:
Sustituye x = 50 en la ecuación:
m = -0,875 (50) + 190
m = 146,25
Por lo tanto, la frecuencia cardíaca máxima permitida es de aproximadamente 146 latidos / min.
2.) Edad para una persona con frecuencia cardíaca máxima de 160 latidos / min:
Sustituye m = 160 en la ecuación:
160 = -0,875x + 190
0,875x = 190 - 160
0,875x = 30
x = 30 / 0,875
x = 34,28
Por tanto, la edad de la persona sería de unos 34 años.

Long term durability constructions of the glass
Answer:
The durability of glass can be witnessed in most cities with ancient churches. Unless broken by excessive loads glass will remain for very long periods. The glass may be pitted by the weather but still it provides service through the centuries of use. The early producers of glass treated the production like alchemy but modern glass is fairly uniform and the properties governed to provide consistent performance in use. Apart from mechanical stress there are only a few factors that damage glass.
