Calculate the rate of heat rejection for the hot fluid (en) and the rate at which the cold fluid receives heat () using your experimental data for Experiments 1 and 2. All physical properties should be calculated at the average fluid temperature. en = m, Cp, AT , On éc = mcCp.CAT AT= (Tc,out - Tein AT, = (Thin - Thout) ) ΔΤ( m; = pV; Vi = 1 t Expt. # Qu[W] Q.
