The container shown below holds kerosene and air as indicated compute the pressure at P,Q,R and S in `KN//m^(2)` take spacific gravity of kerosene as 0.8

Mercury is poured into a U-tube of uniform bore such that the level of mercury remains 20 cm below the open ends in both arms. Now, one arm is filled completely with water and the other arm with kerosene. Calculate the lengths of the water column and the kerosene column. The specific gravities of kerosene and mercury are 0.8 and 13.6 resspectively.

Find the change in the volume of 1.0 litre kerosene when it is subjected to an extra pressure of 2.0xx 10^5 N m^-2 from the following data. Density of kerosene = 800 kg m^-3 and speed of sound in kerosene = 1330 m s^-1

A wide vessel of uniform cross- section with a small hole in the bottom is filled with 40cm thick layer of water and 30cm thick layer of kerosene.The relative density of kerosene is 0.8 .The initial velocity of flow of water streaming out of the hole is (take g=10ms^(-2) )

A cylindrical container has cross sectional area of A = 0.05 m^(2) and length L = 0.775 m. Thickness of the wall of the container as well as mass of the container is negligible. The container is pushed into a water tank with its open end down. It is held in a position where its closed end is h = 5.0 m below the water surface. What force is required to hold the container in this position? Assume temperature of air to remain constant. Atmospheric pressure P_(0) = 1 x× 10^(5) Pa, Acceleration due to gravity g = 10 m//s^(2) Density of water = 10^(3) kg//m^(3)

A rectangular container moves with an acceleration a along the positive direction as shown in figure. The pressure at the A in excess of the atmospheric pressure p_(0) is (take rho as the density of liquid)

Pressure 3 m below the free surface of a liquid is 15KN//m^(2) in excess of atmosphere pressure. Datermine its density and specific gravity. [g = 10m//sec^(2)]

As shown in the figure two cylindrical vessels A and B are interconnected . Vessel A contains water up to 2m height and vessel B contains kerosene . Liquids are separated by movable, airtight disc C . If height of kerosene is to be maintained at 2m , calculate the mass to be placed on the piston kept in vessel B. Also calulate the force acting on disc C due to this mass. Area of piston =100cm^(2) , area of disc C=10cm^(2) , Density of water =10^(3)kgm^(-3) , specific density of kerosene =0.8 .
