URCES Problem 5.64 At steady state, a heat pump provides 30,000 Btu/h to maintain a dwelling at 68°F on a day when the outside temperature is 50°F. The power input to the heat pump is 5 hp. If electricity costs 8 cents per kW h, compare the actual operating cost with the minimum theoretical operating cost for each day of operation. The actual operating cost: $/day. The minimum theoretical operating cost: $/day. By accessing this...

A pump delivers water at 50Cbetween reservoirs differing in elevation by 30[m]. The 0.25[m]diameter commercial steel pipe between the reservoirs is 800[m] in total length with a dis-charge side length of 712[m]. Total minor losses for the system contribute a k coefficient equal to 8. The pump characteristic curve is represented by the equation (in SI units): HP= 35.5 + 165Q−4820Q^2. 1. Compute the match point for the system (operating head and discharge). Provide a graph clearly indicating the match...

A heat pump operating with R-134a is used to maintain an indoor temperature of 21°C using heat from the bottom of a lake that stays at 2°C. Assume an 80% efficient compressor. If the heat pump supplies 100 kW of energy to the building, calculate the required mass flow rate and COP for the heat pump. Calculate a few data points to plot the effect of a 10°C temperature range at the cold side on required mass flow rate and...
