A4 ft high, 3 ft diameter cylindrical water tank whose top is open to the atmosphere initially filled with water. now the discharge plug near the bottom of the tank is pulled nd a water jet whose diameter is 0.5 in streams out. the average velocity of the jet air is approximated as v = (2gh)^1/2, where h is the height of the water in the tank measured from the hole (a variable) and g is the gravitational acceleration. determine how long it takes for the water level in the tank to drop to 2 ft from the bottom.

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
