5.14 Air at I atm and 30°C is forced through a horizontal 30 mm diameter 0.5 m long tube at an average velocity of 0.25 m/s. The tube wall is maintained at 137°C. Calculate (a) the heat transfer coefficient and (b) percentage error if the calculation is made strictly on the basis of laminar forced convection.
