Heated plate area: 10 cm x 10 cm. 2. Tower tunnel cross-sectional area: 12 cm x 15 cm. ST-8= Ts ST-7 = Tinf 1 Results: 1. Determine and compare the total heat transfer rates in the case of natural and forced convections over a heated vertical flat plate. Forced Convection Re Nu h Natural Convection Ra Nu h Qconv Qcony 2. Calculate the combined (forced + natural) Nusselt number and determined the total (combined) heat transfer rate of convection over a heated vertical flat plate. 3. Comment on difference between the forced and free convection.
