Do not evaluate fluid properties at T∞cap T sub infinity end-sub Tscap T sub s alone. You must use the calculated film temperature ( Tfcap T sub f

) , defined as the arithmetic average of the surface temperature ( Tscap T sub s ) and the free-stream fluid temperature ( T∞cap T sub infinity end-sub Do not evaluate fluid properties at T∞cap T

The Problem: "Air flows over a flat plate at a velocity of 5 m/s. The plate is 2m long and maintained at 50°C. The air temp is 20°C. Determine the average friction coefficient and the average convection heat transfer coefficient." The air temp is 20°C

Every problem in the Chapter 7 manual relies on three fundamental dimensionless parameters: Reynolds Number ( Rexcap R e sub x ReLcap R e sub cap L You need to memorize and understand the physical

Chapter 7 is heavy on dimensionless numbers. These are the "shortcuts" engineers use to scale up experiments. You need to memorize and understand the physical meaning of:
