In a hydraulic press

water is flowing in a pipe of radius 2 cm with the average velocity of 15 cm s^-1. What is the nature of flow ? Given coefficient of viscosity of water n is 0.001 kg m^-1 s^-1 and its density is 10^3 kg m^-3 A rectangular film of liquid is extended from (4cm×2cm) to (5cm×4cm). [...]

(a) The flow of blood in an artery of radius 2×10^3 has maintain streamlined. What is the largest average velocity in m/s of blood flow in the artery ? (b) Calculate also the rate of flow of blood in m^3 s^-1 in the artery while streamline flow. Viscosity of blood is 2.084 x 10^-3 pa [...]

What should be the average velocity of water in a tube of diameter 2 cm so that the flow is streamlined ? the viscosity n of water is 0.001 kg m^-1 s^-1 and Reynold’s number Re is 1000. Take density of water to be 10^3 kgm^-3. A rectangular film of liquid is extended from (4cm×2cm) [...]

A liquid is kept in a cylindrical which is rotating at a speed of 4 rps. The radius of the vessel is 0.01 m. Find the difference in height of the liquid at the centre of the vessel and at the side of the vessel. (take pie^2 = 10 and g = 10 m/s^2 ) [...]

In a hydraulic press, cross sectional area of two massless pistons are A1 = 0.3 m^2 and A2 = 0.05 m^2. a block of mass 30 kg is kept over piston of area A1 and 50 kg is kept over piston area A2 as shown. Find the difference in height of the two pistons. The [...]

In a hydraulic press, cross section area of the two massless piston are A1 = 4 cm^2 and A2 = 16 cm^2 15 N force is applied at a smaller piston to support a block of mass m kept on the other piston as shown. How much force is exterted at the other piston ? [...]
