Описание: A metal sheet of area 0.4m^2 is attracted by a force of 0.98N placed over a liquid thin film which lies between sheet and surface of table. The thickness of liquid film is 0.2mm. If the sheet starts its motion with uniform velocity 0.2〖ms〗^(-1), calculate the co-efficient of viscosity of the liquid.
What is the terminal velocity of a rain drop of diameter 0.5mm? The co-efficient of viscosity of air is taken as 1.83×〖10〗^(-5) poise, density of air is 1.3kgm^(-3), density of water is 1000〖kgm〗^(-3) & value of g is 9.8〖ms〗^(-2).
Calculate the average speed of water flowing through a pipe of diameter 10cm and delivered 5m^3 of water per hour.
The speed of water is 0.5〖ms〗^(-1) flowing in a pipe of diameter 5cm. What will be it speed in a pipe of 2.5cm diameter that is connected with it.
Water flows through a horizontal pipe of non-uniform cross section area. The pressure at a point is 130kPa where the velocity is 0.4〖ms〗^(-1). Calculate the pressure at the point where the velocity is 4〖ms〗^(-1).
What will be the gauge pressure in a large fine hose if the nozzle is to shoot water straight upward to a height of 25m?
What is the height of water inside the tank above the orifice if the velocity of efflux of water through orifice is 9.9〖ms〗^(-1).
A liquid of density 8×〖10〗^3 kgm^(-3) is flowing through a horizontal pipe of different cross section. If the pressure difference between two points is 4×〖10〗^4 〖Nm〗^(-2) then what is the speed of liquid in the tube.
An airplane wing is designed such that speed of the air across the top of the wing in 450〖ms〗^(-1) and the speed of the air below the wing is 410〖ms〗^(-1). What is the pressure difference between the top and the bottom of the wings? (Density of air is 1.29kgm^(-3))
