He surface of a cylinder (d = 10 mm) is maintained at 117 °c. fluid flows perpendicularly to the cylinder axis (cross flow). the fluid (37 °c) flows at 5 m/s. for three different fluids (atmospheric air, saturated liquid water, and engine oil), calculate the heat transfer rate per unit length using the churchill-bernstein correlation.

If the temperature goes on increasing with respect to the length (i.e temperature gradient)then it is called positive heat transfer. If the temperature gradient decreases then it is called negative heat transfer.

where are the choices

Explanation:

Your Design Should Work According To These Specifications: 1. ... Your first task is to design a reversible and adiabatic air compressor powered by a steam turbine. Your design ... The compressor should receive 20m^3/s of air delivered at 101 kPa and 25C. 2. The compressed air should exit the compressor at 680 kPa. 3.
