A wet cooling tower is to cool 25 kg/sec of cooling water from 40oC to 25oC at a location where the atmospheric pressure remains constant at 97 kPa. Atmospheric air enters the tower at 25oC and 65% relative humidity and leaves saturated at 35oC. Neglecting the power input to the fan, determine the mass flow rate of the required makeup water.

A natural draft-cooling tower is to remove 50 MW of waste heat from cooling water, which enters the tower at 42 °C and leaves at 27 °C. Atmospheric air enters the tower at standard atmospheric pressure with dry and wet bulb temperatures of 23 °C and 18 °C respectively (approximately 62% relative humidity), and leaves saturated at 37 °C. a) Sketch a fully labelled schematic diagram of the system identifying all the state points.

This is problem 7-13 from El-Wakil’s Powerplant Technology book -- a wet-dry cooling tower receives 20x106 lbm/h of condenser cooling water at 110 degF. The water is cooled in the dry section to 90 degF and in the wet section to 70 degF. The outside air is at 1 standard atmosphere, 60 degF, and 40 percent relative humidity. The air leaves both dry and wet sections at 81 degF. Calculate (a) for the dry section the outside cooling air required,...

QUESTION 15 – COOLING TOWERS AND EVAPORATIVE CONDENSERS A cooling tower is a device that cools a spray of water by passing it through a stream of air. If 15 m3/s of air is at 35 °C dry-bulb and 24 °C wet-bulb temperature and an atmospheric pressure of 101 kPa enters the tower and the air leaves saturated at 31 °C, (a) to what temperature can this airstream cool a spray of water entering at 38 °C with a flow...
