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.
Pressure washer unloaders, unload all the pressure off the pump head when you quit squeezing the spray gun. Pressure regulators leave all the pressure on the pump head while the system is in bypass.We show you how to convert unloader to a regulator. Purchase new unloaders at http://www.steam-brite.com/advanced_s...ressure regulators leave all the pressure on the pump head while the system is in bypass. We show you how to convert unloader to a regulator.
