I am trying to figure of what intake hose sizing I may need to a pump that pumps at much higher flow rates than normal pool pumps. The pump is to be used to basically empty the pump, such as a gasoline powered water pump. I may need to run a long length of suction hose to accomplish what I am trying to do. So, is there a simple online calculator to do this? I assume this is the sort of calculation that is done all the time in calculating total dynamic head. I do not want to create cavitation and I do not want to unnecessarily use a larger diameter suction hose than what is necessary. Thanks.
