An orifice at the bottom of a rectangular tank has a cross-sectional area of 0.004m². The tank has a cross-section of 3m x 2m. a. If it takes 2078 sec. to empty the tank if it contains water at a depth of 5.6m, find the coefficient of discharge. b. Compute the time to lower the water surface from 5.6m to 3m using C = 0.62.

L = 900m D=35cm L=600m L=900m D=75cm D=60cm L=600m D=30cm L=900m D=40cm A flow rate of 0.5 m³/s is branched into three pipes and then rejoined in the concrete parallel pipes as shown in the figure below. Find the head of loss between point A and point B. Here, the coefficient of friction loss in all tubes is 0.03.

Two pipes A and B are connected in parallel between two points M and N as shown in figure. Pipe A is 80 mm diameter, 900 m long and its friction factor is 0.015. Pipe B is of 100 mm diameter, 700 m long and its friction factor is 0.018. A total discharge of 0.030 m³/s is entering the parallel pipes through the division at M. Calculate the discharge in the two pipes A and B. M = 0.015 A fA 80 mm dia, 900 m 100 mm dia, 700 m B fB = = 0.018 N
