![]() ![]() Heat flow rate, Heat flux, Heat generation per unit volume and many more. If calculation is made using the pressure at the point away from the valve, large errors may occur in the calculation results due to pressure loss etc. The calculator below can used to convert between common fluid flow units. The IV Flow Rate Calculator calculates the amount of milliliters per hour that an IV needs to be set to in order to infuse a certain volume of IV. ※3 For P1 and P2, please use pressure close to the valve. Our guide provides handy tables of approximate water flow rates based on pipe size, helping you estimate capacity quickly and easily. Please contact us if the fluid specification requires viscosity correction. By multiplying air velocity by the cross section area of a duct, you can determine the air volume flowing past a point in the duct per unit of time. 16 Nov When it comes to water flow in pipes, determining the capacity depends on the pipe size and water pressure. ![]() ※2 Calculation of viscosity correction is necessary when the fluid is liquid and the kinematic viscosity is 20 mPa・s or more and the calculated Cv value is 0.01 or less. It is a standard for selection of valves, depending on the specific piping conditions and conditions of use, there is a possibility that actual results may differ from calculation results. Flow is the volume of water measured in gallons per hour (GPH) or gallons. 【Explanation of symbols】 QL : Liquid flow rate(h : hours) Qg : Gas flow rate in standard conditions (15℃ 0.1013 MPa abs) P1 : Primary absolute pressure ※3 P2 : Secondary absolute pressure ※3 t : Fluid temperature GL : Liquid relative density(Water = 1) Gg : Gas relative density(Air = 1) 【Notes on use】 ※1 Please handle the calculation result as reference value. Flow Rate Calculator Enter either the pipe diameter and velocity or the volume of fluid passing in a given time to calculate the volumetric flow rate. Use this calculator to estimate the water flow available from your water source. ![]()
