9.7 Consider a large vertical plate with a uniform surface temperature of 130°C suspended in quiescent air at 25°C and atmospheric pressure. (a) Estimate the boundary layer thickness at a location 0.25 m measured from the lower edge. (b) What is the maximum velocity in the boundary layer at this location and at what position in the boundary layer does the maximum occur? (c) Using the similarity solution result, Equation 9.19, determine the heat transfer coefficient 0.25 m from the lower edge. (d) At what location on the plate measured from the lower edge will the boundary layer become turbulent?

A three-cylinder four-stroke engine running at 750 revolutions per minute (rm) consists of cylinders each with a bore diameter 18.50 cm and a piston stroke length of 40.20 cm. During engine testing when the engine is running at 750 revolutions per minute (rpm), a pressure-volume (p-v) indicator diagram is generated and has a mean net area of 6.50 cm? and a diagram length of 3.25 cm. The pressure scale on the indictor diagram is set to 180 kN/m? per cm. Calculate the indicated power in kilowatts (kW) developed by this engine and give your answer to 2 decimal places
