Q3) Water flows through a 10-mm diameter pipe at a flow rate of 1.33x10^4 m/s. Find (a) Velocity of water in the pipe (b) Reynolds Number (Re) for the flow (c) Head loss (hL) due to friction for a length of the pipe. [Physical properties of water: Density = 1000 kg/m^3; Dynamic viscosity = 0.0009 N.s/m^2; g = 9.81 m/s^2] [Equations & Data: Head Loss, hL = (friction factor * (length of pipe * velocity^2))/(2 * g * diameter); Reynolds Number, Re = (density * velocity * diameter)/dynamic viscosity]

Water flows through a pipe of diameter 300 mm with a velocity of 5 m/s. If the coefficient of friction is given by f = 0.015 + 0.08 Re^0.3, find the head loss due to friction for a length of 10 m of this pipe. Take v = 0.01 x 10 m/s.
Adi S.
Find the diameter of a pipe of length 2000 m when the rate of flow of water through the pipe is 200 liters/s and the head lost due to friction is 4 m. Take the value of C = 50 in Chezy's formula.
