Water is conveyed thourth a horizontal tube 8 cm in diameter and 4 kilometer in length at the rate of 20 litre/s Assumming only viscous resistance , callcalute the pressure required to maintain the flow . Coefficient of viscosity of water is 0.001 pa s

Water is conveyed through a tube 8 cm in diameter and 4 km in length at the rate of 120 litres per minute. Calcualte the pressure difference required to maintain the flow. Coefficient of viscosity of water = 0.001 SI units. [Hint" " V=(piPr^(4))/(8etal) ]

Water is conveyed throuh a uniform tube of 8 cm in diameter and 3140 m in length at the rate 2 xx 10^(-3) m^(3) per second. The pressure required to maintain the flow is ( viscosity of water = 10^(-3) )

Water at 20^(@) C is escaping from a cistern by ways of a horizontal capillary tube 10 cm long and 0.4 mm in diameter ,at a distance of 50 cm below the free surface of water in the cistren .Calculate the rate at which the water is escaping .Coefficient of viscossity of water at 20^(@)C =0.001 decapoise .

water flows through a horizontal tube of length 20cm and internal radius 0.081 cm under a constant head of the liquid 20cm high. If 864 cm^3 of water issues from the tube in 12 minutes, calculate the coefficient of viscosity of water. Density of water=1g cm^(-2) and g =981cm^(-3)

Calculate the mass of water flowing in 10 minutes throuth a tube 1 mm in diameter and 0.40 m long ,if there is a constant pressure heat of 20 cm of water . Coefficient of visosity of water is 0.00089 Pas.

Water flows through a horizontal pipe of varying cross-section at the rate of 20 litres per minuts , determine the velocity of water at a point where diameter is 4 cm
