The shear stress at a point 4 cm from the pipe wall is 0.002 kgf/cm2 . Calculate the shear stress at the pipe wall. 6. (a) Derive an expression for head loss due to friction in pipes. (b) A horizontal pipe of diameter 40cm is suddenly contracted to a diameter of 20cm. The pressure intensities in the larger and smaller pipe is given as 1.5 kgf /cm2 and 1.30kgf /cm2 respectively. If CV = 0.62, find the loss of head due to contraction. Also determine the rate of flow of water. 7. Explain the principle and working of the following with the help of neat sketches. 1 of 2
