Experiment-l Parallel and Counter Flow Heat Exchange in Concentric Tube Heat Exchanger Purpose of the experiment: Calculation of the heat transfer rate () and the log mean temperature difference (AT)m for a concentic tube heat exchanger in parallel and counter flovw Procedure the main power 2) Turn on the heater and the pump. Choose parallel flow from the control panel. 3) Adjust the flow rate of water to 300 (liters/h) 4) Adjust the temperature to 50 (°C) 5) When the system becomes stable, record the temperatures and flowrate on the table below 6) Press the counter flow button on the control panel. 7) When the system becomes stable, record the temperatures and flowrate on the table beloW Calculations * Calculate the heat transfer rate for parallel (Qparallel) and counter flow (cnter) heat exchanger modes from the water side. (q = mwater × CP,water × (AT (For the specific heat value (cp) of water use the average of water inlet and outlet temperatures) Draw the temperature vs. heat exchanger pipe length graphic for both parallel and counter flow heat exchanger modes Calculate the log mean temperature difference (AT)m for both parallel and counter flow heat exchanger modes Given: mwater (kg/s)-a(kg/m3) × Q(m3/s) Unit conversion: 1 (m3) 1000(liters) Data Sheet → Density (p) should be taken at the average of water inlet and outlet temperatures Parallel flow 50.6 49.1 Counter flow Hot oil inlet temperature, ti (C) Hot oil outlet temperature, t2 (C) Cold water inlet temperature, t3 (C) Cold water outlet temperature, t4 C) Heater power, Pi (W) Volumetric flow rate of water liters/h) 51.0 49.5 13.2 21.7 14.3 13.5 727.2 756.8 300 300
