Experimental measurements of the convection heat transfer coefficient for a square bar in cross flow yielded the following values:
h1=50 W/m^2⋅K when V1=20 m/s
h2=40 W/m^2⋅K when V2=15 m/s
Assume that the functional form of the Nusselt number is
¯¯¯¯¯¯¯¯
Nu= C Re^mPr^n
where C, m, and n are constants.
a. What will be the convection heat transfer coefficient for a similar bar with L = 1 m when V = 15 m/s?
b. What will be the convection heat transfer coefficient for a similar bar with L = 1 m when V = 30 m/s?
c. Would your results be the same if the side of the bar, rather than its diagonal, were used as the characteristic length?

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Modern high speed trains do not have perpendicular expansion gaps where rails are joined end-to-end any more they are mostly welded together but what might happen if there was a spell of particularly hot weather that causes inspection of the tracks?
