Total rate of heat transfer as a function of mass flow rate

Assignment Help Mathematics

Question: Reconsider Problem. Using the EES (or other) software, evaluate the effect of glycerin mass flow rate on the surface temperature of the parallel plates and the total rate of heat transfer necessary to keep the outlet mean temperature of the glycerin at 35°C. By varying the mass flow rate from 0.05 to 6 kg/s, plot the surface temperature of the parallel plates and the total rate of heat transfer as a function of the mass flow rate.

Problem: Glycerin is being heated by flowing between two parallel 1-m-wide and 10-m-long plates with 12.5-mm spacing. The glycerin enters the parallel plates with a temperature of 25°C and a mass flow rate of 0.7 kg/s. The plates have a constant surface temperature of 40°C. Determine the outlet mean temperature of the glycerin and the total rate of heat transfer. Evaluate the properties for glycerin at 30°C. Is this a good assumption?
