An office building is served by an air-cooled chiller currently operating at 115 tons (404.5 kw). the measured chilled water supply temperature is 43°f (6.1°c), and the measured chilled water return temperature is 57°f (13.9°c). what is the estimated chilled water flow rate through the chiller? a. 172 gpm (10.9 l/s) b. 197 gpm (12.4 l/s) c. 212 gpm (13.4 l/s)

B.197 gpm and 12.4 L/s

Explanation:

Given that

Load Q = 404.5 KW

Water inlet temperature= 6.1 °C

Water outlet temperature= 13.9°C

We know that specific heat for water

Now from energy balance

by putting the values

    (1 Kg/s = 15.85 gal/min)

We can say that

We know that

12.38=1000 x volume flow rate

So

volume flow rate = 12.38 L/s

So the option B is correct.
