Seeking help to calculate head pressure
Thread Content
Toluene is to be transported at a flow rate of 30 cubic meters per hour, to a height of 15 meters. The density of the liquid is 0.87, the length of the pipeline is 300 meters, there are 15 elbows, 4 tees, and 3 valves. How should the head pressure be calculated? What should the head be?
Pipe calculation formula: Each elbow valve is counted as 1 meter; the height is 15, plus 15 for the elbow and 3 for the valve, resulting in 33. The actual value ranges from around 35 to 40. The head pressure is calculated as pump outlet pressure × 10. Outlet pressure = inlet pressure + density of the material being transported × 9.8 × head pressure. I use this formula to calculate the performance of water pumps; you can refer to it as a guide.
