C in heat transfer
WebJun 30, 2024 · Temperature difference, T h – T c = 100 °C – 0 °C = 100 °C. Time of heat transfer, t = 1 hr = 3600 s. Amount of heat transfer, Q = m L = 4000 × 80 = 320000 cal. Heat transfer rate, q = Q ⁄ t = 320000 cal ⁄ 3600 s = 89 cal ⁄ s. The formula for heat transfer rate is given as: q = K A (T h – T c) ⁄ d. Rearrange the above formula ... WebInitially, when the rate of heat transfer is high, the hot water has a temperature of 70°C and the cold water has a temperature of 5°C. The two containers have a 65°C difference in temperature. As the hot water begins to cool and the cold water begins to warm, the difference in their temperatures decrease and the rate of heat transfer decreases.
