WebSep 5, 2024 · So far I have used the Boyles Law which assumes that PV/T = constant which gets us P1 * V1 = P2 * V2 and PdV+VdP = 0 I formed this over to PdV=VdP. and divided by the change in time to get dV/dt = - VdP/Pdt Could anyone help me and tell me if I am on the right track here or have I overlooked something. Answers and Replies Sep 4, 2024 #2 WebThere is no scientific definition of the volume of a faucet drip, but after measuring a number of kitchen and bathroom sink faucets, for our calculations below (numbers are rounded), we are going to use 1/4 milliliter (ml) as the volume of a faucet drip. By these drip estimates: One gallon = 15,140 drips One liter = 4,000 drips
WebA leak rate of Q L = 1 mbar · l/s is present when in an enclosed, evacuated vessel with a volume of 1 l the pressure rises by 1 mbar per second or, where there is positive pressure in the container, pressure drops by 1 mbar. The leak rate Q L defined as a measure of leakiness is normally specified in the unit of measure mbar · l/s. WebThe leak cost formula is the number of leaks * leakage rate (CFM) * (kW/CFM) * operating hours per year * ($/kWh).
