A chimney as shown in the figure requires to have natural draft (pressure difference between the furnace and the bottom of chimney, P0 - P1) of 1.0133 × 103 Pa.
Given: acceleration due to gravity, g = 9.81 m⋅s-2
Assume densities of air and flue do not change along the chimney height. Neglect frictional energy loss and kinetic energy difference at the bottom and top of the chimney.
If the density difference between the air and flue is 0.5 kg⋅m-3, the minimum height (h) of the chimney in meters is _______ (round off to nearest integer).
