WitrynaThe inlet temperatures on hot and cold sides are 75°C and 20°C respectively. The exit temperature of hot water is 45°C. Calculate LMTD of heat exchanger. Q7. Saturated vapor at 200 °C condenses to saturated liquid at the rate of 150 kg/s on the shell side of a heat exchanger (enthalpy of condensation hfg = 2400 kJ/kg). WitrynaIn a parallel flow heat exchanger, if the outlet temperature of hot and cold fluids are the same, then the log mean temperature difference (LMTD) is. Air is to be heated by condensing steam. Two heat exchangers are available (i) a shell and tube heat exchanger and (ii) a finned tube heat exchanger. Tube side heat transfer area are … swivel sentry

Witryna18 lip 2015 · A liquid-to-liquid counterflow heat exchanger is used to heat a cold fluid from 120 °F to 310 °F. Assuming that the hot fluid enters at 500 °F and leaves at 400 °F, calculate the log mean temperature difference for the heat exchanger. The given answer is 232 °F. I used: LMTD = max − min ln( max min) max = 500 − 120 = 380 min = 400 … Witryna1 wrz 2024 · Topic DiscussDerivation of Logarithmic Mean Temperature Difference (LMTD) for counter flow heat exchanger For E-Content : http://krunalkhiraiya.weebly.com/e-... The logarithmic mean temperature difference (also known as log mean temperature difference, LMTD) is used to determine the temperature driving force for heat transfer in flow systems, most notably in heat exchangers. The LMTD is a logarithmic average of the temperature difference between the hot and cold feeds at each end of the double pipe exchanger. For a given heat exchanger with constant area and heat transfer coefficient, the larger the LMTD, the more heat i… texas tech scd in pt
