A water stream is heated in fully developed flow through a pipe with uniform heat flux at the wall. The flow rate is m=10g/s, the heat flux q"=0.1 W/cm2, and the pipe radius r0=1cm. The properties of water are μ=0.01 g.s/cm and k=0.006 W.K/cm.
a) Caculate the Reynold number based on pipe diameter and mean fluid velocity.
b) Calculate the heat transfer coefficient.
c) Caculate the difference between the wall temperature and the mean (bulk) fluid temperature.
