e diameter of an open-topped tank 1.5 m high increases uniformly from 4.2 m at th se to 6 m at the top. Discharge from the base of the tank takes place through mm diameter pipe which is 3 m in length. The pipe discharges the water to th nosphere 1.5 m below the base of the tank. Initially, the tank is fully filled with wate ke f = 0.01. Find the time to empty the tank. %3D

Question
1.1 Find the rate at which water will flow in each pipe, ignoring the shock losses at P and entry to pipelines A and B. 1.2 Find the pressure at P. QUESTION 2 The diameter of an open-topped tank 1.5 m high increases uniformly from 4.2 m at the [2 base to 6 m at the top. Discharge from the base of the tank takes place through a 75mm diameter pipe which is 3 m in length. The pipe discharges the water to the atmosphere 1.5 m below the base of the tank. Initially, the tank is fully filled with water. Take f = 0.01. Find the time to empty the tank. QUESTION 3 Water must flow over a distance of 2 800 m from a large catchment dam to a turbine. [10 The water level in the catchment dam is 1 620 m above sea level and the turbine is situated 1 275 m above sea level. The efficiency of transmission is 65% and 300 kW must be transmitted from the pipeline to the turbine. Iff = 0.007, determine the number of 200 mm diameter pipelines, which must be laid in parallel, needed to transmit the required power. rch
