Problem 1 (40 points) Consider the following chilled water system. The chiller draws 155 kW of electric input power. The chiller evaporator (cooler) pressure drop curves are provided below in units of feet of water column (ft wg) and gallons per minute (gpm) on a logarithmic scale. The chiller model number is 106. The system's minimum flow bypass is installed to ensure a manufacturer minimum flow rate of water through the chiller to prevent freezing at low loads. CWR 85F (- Cooling Tower 72F CWS CW Pumps Estimate the following. a. Chilled water flow rate through the chiller in gallons per minute b. Chiller evaporator load in tons c. Cooling tower load in tons d. Condenser water flow rate in gallons per minute e.
