(This is Problem 6-91 in the textbook). Air at 1 atm is flowing over a flat plate with a free stream velocity of 70 m/s. If the convection heat transfer coefficient can be correlated by Nux = 0.03 Rex 0.8 Pr1/3, Determine the friction coefficient and wall shear stress at a location 2 m from the leading edge. Evaluate fluid properties at 20°C.

answer:

Power braking's benefits

Among the big advantages of a power braking system are it's: Regarded as safer. The heat caused by the friction of drum brakes causes them to wear down. Because disc brake systems have better heat distribution, they're more efficient
