How to Calculate Instantaneous heat transfer rate?
Instantaneous heat transfer rate calculator uses Heat Rate = Convection Heat Transfer Coefficient*Surface Area*(Initial Temperature-Fluid Temperature)*(exp(-(Convection Heat Transfer Coefficient*Surface Area*Time Elapsed)/(Density*Total Volume*Specific Heat Capacity))) to calculate the Heat Rate, The instantaneous heat transfer rate formula calculates the rate of heat transfer at the given instant when a lumped body is going for unsteady-state heat conduction. Heat Rate is denoted by Qrate symbol.
How to calculate Instantaneous heat transfer rate using this online calculator? To use this online calculator for Instantaneous heat transfer rate, enter Convection Heat Transfer Coefficient (h), Surface Area (A), Initial Temperature (To), Fluid Temperature (tf), Time Elapsed (t), Density (ρ), Total Volume (VT) & Specific Heat Capacity (Co) and hit the calculate button. Here is how the Instantaneous heat transfer rate calculation can be explained with given input values -> 7.155337 = 0.04*18*(20-10)*(exp(-(0.04*18*12)/(5.51*63*4))).
