Question:

A rectangular bar with a characteristic length of 0.5 m is placed in a free stream flow where the convection heat transfer coefficients were found to be 100 W/m2 · K and 50 W/m2· K when the free stream velocities were 25 m/s and 5 m/s, respectively. If the Nusselt number can be expressed as Nu = C Rem Prn, where C, m, and n are constants, determine the convection heat transfer coefficients for similar bars with

(a) L = 1 m and V = 5 m/s,

(b) L = 2 m and V = 50 m/s.
