for Heat Exchanger Design & Calculations.Q1 = Density x Heat capacity x ( 1 - 2 ) x 3 / 3600 [kW] Q2 = Density x Heat capacity x ( 5 - 4 ) x 6 / 3600 [kW] (For water, density is 1000, and heat capacity is 4.186kJ/kg deg.C.) The heat duty on hot side (Q1) is equal to the heat duty on cold side (Q2); Q1 and Q2 must be the same (Q1 = Q2). We therefore introduce the specific heat capacity, c, which differs from one substance to the next, and which completes the relationship between heat transferred and temperature change: (5.3.3) Q = m c Δ T The mass is always a positive quantity, and we define the specific heat capacity as a positive value, which means that Q > 0 when Δ T > 0.
