A 300-HP engine with a thermal efficiency of 30% is using a remote radiator which absorbs 25% of the heat supplied to the engine. Cooling system with cooling tower is used with a cooling range of 5°C. The temperature rise of the water after passing the remote radiator is 10°C. Air enters the cooling tower at 32°C dry-bulb; 26°C wet-bulb temperatures and leaves the tower at 36°C & 70%RH. Make a schematic diagram of the system, the process in the provided psychrometric chart and calculate the following: (a.) The water flow rate in the cooling tower in liters per hour, and (b.) If the heat absorbed by air is 20% of heat absorbed by the cooling tower water, what is the air flow needed in cu.m/hour.

B- A steam generation unit in power plant operates at a constant pressure of (10 bar) and the water evaporates at the rate of (0.9 from the total mass flow rate of water). Inlet and leaving water enthalpy are (200 kJ/kg) and (2000 kJ/kg) respectively. The inlet and outlet velocity are (10 m/s) and (25 m/s) respectively. If 80% of the heat energy supplied to the steam generation unit is used in evaporating the fluid. Determine the heat evaporation and work done if the inlet and outlet diameter are the same level. The fuel produces 28000 kJ of heat energy for one kg and the mass flow rate of water is 1000 kg/h.
A chemicals company wants to optimize the power consumption of their air compressors. Their Design Engineers proposed to replace their Single-stage Adiabatic Compressors with the following: a. Isothermal Compressorb. Two-stage Compressor with intercoolingc. Four-stage Compressor with intercooling In order to justify the replacement, the percentage of the energy per mass (J/g) saved by each proposed compressor system should be calculated. Savings should be at least 40%. Determine which of the three proposed compressors will meet the criterion. The flow rate of air required is 600 ft3/min at 70 °F and 14.7 psi, which should be compressed to a final pressure of 2,000 psig. The relative molecular mass of the gas is 28, isentropic constant is 1.40, and density of air is 1.204 kg/m3.
