A 4000-km2 watershed receives 102 cm of precipitation in one year. The average flow of the river draining the watershed is 34.2 m3/s. Infiltration is estimated to be 5.5 x 10-7 cm/s and evapotranspiration is estimated to be 40 cm/year. Determine the change in storage in the watershed over one year. Group of answer choices

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
