A chimney of height 45 m is full of hot gases at temperature 330°C. If the discharge through the chimney is maximum, determine the draught in terms of column of hot gases. The ambient is 25°C.

A chimney of height 45 m is full of hot gases at temperature 330°C. If the discharge through the chimney is maximum, determine the draught in terms of column of hot gases. The ambient is 25°C. Correct Answer 45 m

H = 45 m, Tg = 330°C or 603 K, Ta = 25°C or 298 K Since it is given that the discharge though the chimney is maximum. Draught in terms of column of hot gases, H1 = H (Chimney height) H1 = 45 m.
