Temperature Distribution in Flow Direction (2)

q”=h(TO-T?)=2230 (W/m2),

R=0.02 (m), dm/dt=0.05 (kg/s),

cp=4200(J/kg K)

Tz(z)=Tz(0)+0.212z=20+0.212z

• Temperature increases linearly. It increases 0.212°C for every 1 m increase in length. The temperature increase in water can be significant if the tube length is long.
