A piston, when positioned at the 4cm mark, traps a volume V of gas inside the pump at 75 degrees Celsius and 100kPa.
a.) Calculate the volume V given that the cross sectional area of the piston is 10cm^3.
b.) The end of the pump is sealed and the temperature of the gas decreased to 27 degrees Celsius while the pressure increased by 50kPa.
Calculate the new volume of the gas.

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio ρ1/ρ2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?
