chine that can produce up to 580 kJ of work by taking waste heat from a melting furnace (temperature 1530 °C) throws the heat that it cannot use into a chemical system at 67 °C. Which of the following is the heat taken by this heat machine from the oven?

.

A potential difference of 120 V is established beween two parallel metal plates. The magnitude of the charge on each plate is 0.020C. What is the capacitance of this capacitor? a) 170 uC b) 24 uC c) 7.2 uC d) 0.12 C e) 2.4 C Please show your work Thanks

Please answer legibly.  Heat and Mass Transfer - Heat Exchanger Water at 95°F is heated with steam up to a temperature of 212°F. The mass of water is 110 lb and the heating times takes 1200s. a) Find the heat transfer rate of the process. Assuming 1-1 heat exchanger. b) Calculate the total area from a) given overall heat transfer coefficient is 14 BTU/hr·ft2·°F  c) From b), how many tubes of 2.5 in diameter and 12ft length should be used?
