Question

300 kg/min of water is required to be cooled from 50°C to 25°C in a wet cooling tower. For these purposes, 730 m³/min of atmospheric air is circulated through it at countercurrent. If the atmosphere is at a pressure of 94 kPa and the dry bulb and humid are 25°C and 15°C, respectively, and in the mixing process 3.7% of water is lost per evaporation, determine*:
a) Relative and absolute humidity and dew temperature of the atmosphere.
b) Absolute humidity and temperature of the air at the outlet.

Expert Solution

Step 1: Introduction

To calculate the relative, absolute humidity, and dew point temperature of the atmosphere and absolute humidity and temperature of the air at an outlet

given, the dry bulb temperature $t subscript d space equals 25 space C$

the wet bulb temperature $t subscript w space equals 15 space C$

atmospheric pressure $p equals 94 space k p a$
