Problem 01Water from a large reservoir is discharge to atmosphere through a 100 mmdiameter pipe and 450 m long. The entry from the reservoir to the pipe issharp and the outlet is 12m below the surface level in the reservoir. Takingf=0.01 in the Darcy formula, calculate the discharge.Problem 02Water is discharged from a reservoir into the atmosphere through a pipe 39mlong. There is a sharp entrance to the pipe and diameter is 50 mm for 15 mlong from the entrance. The pipe then enlarge suddenly to 75 mm in diameterfor the remainder of its length. Taking into account the loss of head at entryand at the enlargement, calculate the difference of level between the surfaceof the reservoir and the pipe exit, which will maintain a flow of 2.8 dm³/sec.Take f as 0.0048 for the 50 mm pipe and 0.0058 for the 75 mm pipe.Problem 03VdWater is pumped with a velocity 2, 8 m/s in a 150 mm diameter pipe. TheH₂branches at A into a 75 mm diameter pipe, 50 m long with f-0,008, and athe100 mm diameter pipe, 170 m long with f= 0,007, which joins up again intodua 150 mm diameter pipe. Point A is 5 m higher than point B. Determine:(a) The flow rate in each pipe & the pressure at B if the pressure at A is450 kPa.7| Page
