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 Pr, 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/m²K.
A 200mm diameter spherical steel ball initially at 500°C is rapidly immersed in an oil bath that is at 20°C. The convection coefficient is h = 600W/m²-K, and the steel ball has the following properties: c= 500J/kg-K, p= 7000kg/m³, k=30W/m-K. Determine the time taken (min) for temperature at the surface of the ball to drop to 100°C.
