# mass flow rate of cooling water equation

The conservation of mass is a fundamental concept of physics. { The higher the temperature of cooling water at the condenser inlet is, the higher the pressure of the condensing steam becomes [2][3][4][5]. The total power in due to heat and mass flow through the inlet port (1) must equal the total power out due to work and mass flow through the outlet port (2), thus: Example: Once you have the value place your engines brake Power (in KW) and compute the heat flow needed to remove (Q dot = value X power [KW]). per second and the density is in pounds-mass per cubic (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){ The mass flow rate is related to the volumetric flow rate as fluid. There is an elementary equation from basic thermodynamics that states that the rate of heat transfer (Q) equals the mass flow rate (M) times a Constant (the specific heat of water) times the Delta T (fluid temp out minus fluid temp in): Q = M x C x Delta T In other words, the rate of heat transfer is directly proportional to mass flow rate. We could manipulate the specific heat capacity only by changing the fluid used in the loop. if (document.getElementById("tester") != undefined) The evaporator water flow rate can be calculated . } // -->, GD&T Training Geometric Dimensioning Tolerancing. Advertising "+ (dt.getFullYear()) +" "+ (("0"+dt.getHours()).slice(-2)) +":"+ (("0"+dt.getMinutes()).slice(-2)); Engineering Calculators rate. •Heat … ; }, Fluid Flow Table of Contents The SI unit for flow rate is m 3 /s, but a number of other units for Q are in common use. Disclaimer Mass flow rate can be calculated by multiplying the volume flow rate by the mass density of the fluid, ρ. The rate of flow of oil is 1 kg/s. Training Online Engineering Power= (dm/dt) (latent heat of vaporisation). m dot is the mass flow rate (gm/sec) C p is the specific heat of water (4.186 J/gm deg C) The calculator below can be used to determine the temperature delta or rise for a given cooling water application (heat load or power dissipated and cooling water flow rate) using the first formula above. document.write(' ') document.write('
