In a double-pipe heat exchanger of 10 m length, a hot fluid flows in the annulus and a cold fluid flows in the inner pipe. The temperature profiles of the hot (Th) and cold (Tc) fluids along the length of the heat exchanger (x, such that x≥0), are given by
Th(x)=80-3x
Tc(x)=20+2x
where Th and Tc are in °C, and x is in meter.
The logarithmic mean temperature difference (in °C) is
Th(x)=80-3x
Tc(x)=20+2x
where Th and Tc are in °C, and x is in meter.
The logarithmic mean temperature difference (in °C) is
Correct : b
