Assuming that the total value is in cell A2 and percent in B2, the above formula turns into a simple =A2*B2 and returns 104.50. Remember, when you type a number followed by the percent sign (%) in Excel, the number is interpreted as a hundredth of its value. For example, 11% is actually stored as 0.11 and Excel uses this underlying value in all formulas and calculations. In other words, the formula =A2*11% is equivalent to =A2*0.11.
from my understanding, shut off pressure is the the higest pressure that can be produced by a pump and this happened at zero flow i.e. control valve closed at discharge line. so when pump running during discharge valve closed, the pressure build up in the pipe line until a maximum pressure and this maximum pressure is shut off pressure.
Unloader Valves. Unloader Valves are the traffic directors of your pump and pressure regulator. They serve to direct the flow of water in a pressure washer system. When water stops flowing from the nozzle of a spray gun, the unloader valve redirects it for a safe pressure outlet. When the cleaner is in âbypass mode,â water that is not released by the spray gun is diverted back to the inlet side of the pressure pump.
