Ram a farmer, managed to grow shaped-watermelons inside glass cases ofdifferent shapes. The shapes he used were: a perfect cube, hemi-spherical, cuboid,cylindrical along with the normal spherical shaped watermelons. Thickness of the skinwas same for all the shapes.

4) One measure of the scale of a process is its throughputs of fuel or other input raw materials, e.g., lbs of coal per hour. Compare the coal throughputs for a small-scale experiment that uses 10 mg of coal in 6 seconds, and a single boiler in a large commercial-scale central-station electric generating plant. Assume: the commercial facility has a total output of 1,020 MW e supplied by three boilers of equal capacity; the boiler has a heat rate of (8,980 Btu th /hr)/(kW e ) based on fuel HHV, and fires coal with a gross heating value (i.e., HHV) of 14,000 Btu th /lb.
