Water pumps use electrical energy to create mechanical energy needed to move water. A 1875 W water pump is plugged into a 110 V electrical outlet.

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference

This is the number of complete movements of a wave per second.
