HW11 HW11HW11 1. A condenser coil has been tested at the following conditions: a) 43 oC condensing temperature, b) entering air temperature of 32 oC, and c) volumetric flow rate of 0.566 m3/sec. At these conditions, the leaving air temperature is 40 oC. Estimate the average overall heat transfer conductance for the coil. Determine the coil heat transfer effectiveness associated with these conditions. 2. An evaporator coil has been tested at the following conditions: a) 7 oC evaporating temperature, b) entering air dry bulb temperature of 27 oC, c) entering air wetbulb temperature of 20 oC, and d) volumetric flow rate of 0.566 m3/sec. At these conditions, the leaving air temperature is 13 oC and leaving relative humidity is 90%. Estimate the average overall heat and mass transfer conductance for the coil. Determine the overall coil heat and mass transfer effectiveness associated with these condition
