1.Water flows through a pipe of diameter 0.1m with a velocity of 4m/s.If the pipe branches into smaller pipes of diameter 0.03m and 0.02m,What is the ratio of the flow rates in the two smaller pipes?
2.A cylinder tank of radius 2m is filled with water to a height of 3m.What is the pressure at the bottom of the tank?
3.A 5cm diameter cylinder filled with water is placed on a smooth surface and a horizontal force of 50N is applied on the top of the cylinder and the surface is 0.4,what is the minimum force required to make the cylinder slide?
4.A fluid with a density 800kg/m3 flows through a horizontal pipe of diameter 0.1m with a velocity of 5m/s.If the pipe bends at a right angle,what is the pressure drop at the end?
5.A fluid with a density of 800kg/m3 flows through a horizontal pipe of diameter 0.1m with a velocity of 3m/s.If the pipe is suddenly closed by the valve how long will it take for the pressure at the closed end to reach 90% of the initial pressure?
