Required information 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 coefficient for similar bar where L = 1 m and V=14 m/s. (Round the final answer to one decimal place.) The convection heat transfer coefficient is 105 W/m².K.

Transcribed Image Text:**Required Information**
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 * Re^m * Pr^n, where C, m, and n are constants.
**Task**
Determine the convection heat transfer coefficient for a similar bar where L = 1 m and V = 14 m/s. (Round the final answer to one decimal place.)
**Solution**
The convection heat transfer coefficient is 105 W/m²·K.
