A 175 kilogram/385 pound cement block that displaces 115 litres/4 cubic feet of water lies on the bottom in 14 metres/46 feet of salt water. What is the minimum amount of water that must be displaced from a lifting device to bring the block to the surface?

Amanometer is used to measure the air pressure in a tank. the fluid used has a specific gravity of 1.25, and the differential height between the two arms of the manometer is 34 in. if the local atmospheric pressure is 12.7 psia, determine the absolute pressure in the tank for the cases of the

Aquantity of gas has a volume of 1.5 m3 and an absolute pressure of 95 kpa. when the gas is compressed to a volume of 0.5 m3, what is the new absolute pressure of the gas? (assume that there’s no change in temperature.)
