A tank is filled with water of density 10^(3)kg//m^(3) and oil of density 9xx10^(3)kg//m^(3) .The height of water layer is 1 m and that of the oil layer is 4 M . The velocity of efflux front an opening in the bottom of the tank is

A tank is filled with water of density 1 g cm^(-3) and oil of density 0.9 g cm^(-3) . The height of the water layer is 100 cm and of the oil layer is 400 cm. If g = 980 cm s^(-2) , then the velocity of efflux from an opening in the bottom of the tank is

A rectangular bar of soap has density 800kg//m^(3) floats in water density 1000kg//m^(3) . Oil of density 300kg//m^(3) is slowly added, forming a layer that does not mix with water. When the top surface of thhe oil is the some level as the top surface of the soap. What is the ratio of the oil layer thickness to the soap's thickness. x//L ?
