- Water at 5°C is to be pumped from the river to the bottom of a water tower. The pump is 5 m above the river (dimension "a" on the diagram below) and is supplied by a 6.00 inch schedule 40 pipe. The tank is 19.5 m above the pump (dimension "b" on the diagram below) and is supplied by a 4 inch schedule 40 pipe. The water level in the tank is 4.3 m above the inlet (dimension "c" on the diagram below). The pump delivers 0.021 m/s. Losses are estimated to be 1.2 m between the river and the pump, and 4.2 m between the pump and the tank.

- For the single pump-pipe system below, what will be the changes for the operating point if we increase the pipe size but decrease the shaft speed of the pump? EB H₂ O The operating point will remain the same. O The operating point will occur either at a higher discharge or at a lower discharge, depending on the specific influence of each change. O The operating point will occur at a higher discharge. O The operating point will occur at a lower discharge.arrow_forwardA surface condenser deals with 12000 kg of steam per hour. Air leakage into the condenser is found to be 4 kg/hr. The vacuum and temperature at the air pump suction are 700 mm of Hg and 36°C respectively. The barometric pressure is 760 mm Hg.

Water from this tank is pumped into the nozzle when needed use. This fire suppression system is designed to be able to transmit 1890 L/min of water at a pressure of 15 bar (relative pressure). If we ignore the difference in height between the water level in the tank and pump, there is no change in diameter of pipe and nozzle, pump efficiency is 70%.
