Pipe Sizing Charts help to determine the optimal size and material of a pipe used with a solar water pump system. This is a highly practical and reliable calculator which can be simply used for calculating the pipe size depending on mass flow rate and stream velocity. 1 m 3 /h of water is pumped a head of 10 m. The theoretical pump power can be calculated as. The cost calculator will tell you the electrical cost of running your pond monthly or annually, you can also use this calculator for … The pipe is 12 feet long, and the difference in height between the beginning and end points of the pipe is equal to 3 feet.
