1- A 100 m long pipe is used to fill a water tank at the far end of a land from the main water pipe in the front of the land. The pressure at the main water pipe is 250 kPa. If the pipe diameter is D = 5.0 cm and its inner roughness is &= 0.2 mm find the flow rate into the tank when the water surface in the tank is 5 m above the main water pipe. (15 points) Ignore the minor losses. Assume density of water is p = 1000 kg/m and dynamic viscosity of water is = 10- N.s/m. Main water Pipe
