Calculate the surface area needed to power a 45-hp pump capable of delivering up to 38,000 liters/min ofwater at noon in Albuquerque, NM. Assume a heat rejection temperature of 305 K and that the ORC engine works at 60% of the Carnotefficiency.

Acompressor compresses a gas, a pump compresses a liquid. for a given pressure ratio, why does it take more work to compress a gas in a compressor than a liquid in a pump? a)- for a given pressure ratio the average specific volume for a gas is much higher than the average specific volume for a liquid. b)- there is no difference. the only difference is the amount of heat generated (not work) c)- for a given pressure ratio the average volurge for a gas is much higher than the average volume for a liquid. d)-there is no difference
