2. A water pump that consumes 2 kW of electric power when operating is claimed to take in water from a lake and pump it to a pool whose free surface is 30 m above the free surface of the lake at a rate of 50 L/s.

To find the reactance XLXLX_L of an inductor, imagine that a current I (t) = I0sin (ωt) I (t) = I0sin⁡ (ωt), is flowing through the inductor. What is the voltage V (t) V (t) V (t) across this inductor?

Hydraulic engineers often use, as a unit of volume of water, the "acre-foot", defined as the volume of water that will cover 1 acre of land to a depth of 1 ft. A severe thunderstorm dumps 2.6 in. of rain in 30 min on a town of area 28 km2.

A completely reversible heat pump produces heat at a rate of 100 kW to warm a house maintained at 25℃. The exterior air, which is at 0℃, serves as the source.

A closed system undergoes a process in which work is done on the system and the heat transfer Q occurs only at temperature Tb. For each case, determine whether the entropy change of the system is positive, negative, zero, or indeterminate.
