FIRST LAW OF THERMODYNAMICS CONSERVATION OF ENERGY – OPEN SYSTEM A pump in a municipality's water supply system receives water from the filtration beds and pumps it up to the top of a water tower. The tower's height is 35 m, and the inlet piping to the pump is 2 m below the pump's intake. The water temperature is 20 °C, measured at both the inlet and discharge from the pump. The mass flow rate through the pump is 100 kg/s' the diameter of the inlet piping is 25 cm, and the diameter of the discharge piping is 15 cm. Assuming that there is no heat transfer and no change in internal energy of the water, determine the power required by the pump. Ans: -37.68 kW

Show your complete solution for each problem. Only the final answer in your calculation should be rounded off to two decimal digits. Box your final answer. 1. The increase in the specific internal energy is 33.8 BTU/Ibm in a reciprocating compressor draws 40 lbm/min of air whose density is 0.074 lbm/ft³ and discharge it with a density of 0.311 lbm/ft³. At the suction, the pressure is 18 lb:/in² and discharge 88 lb:/in². If the changed in kinetic energy was neglected, determine the work on the air in horsepower (hp).
Based on the mechanisms of thermal energy exchange what would happen if you exercised in a colder place where it's 5⁰C.
