The world's tallest stack is the GRES-2 Power Station in Kazakhstan 419.7 m high. Assume that the inner diameter of the stack at the top is 16.8 m. The temperature of the gas is 140 C and the velocity is 22 m/s as it exits the stack. The ambient temperature is 16 C. The wind speed at the stack height is 12 m/s. Use the Briggs model to estimate the plume rise. The Stability Classification is F. The atmosphere is stable and isothermal. (a) The bouyancy flux parameter, F, is Submit Answer Incorrect. Tries 1/10 Previous Tries (b) The stability parameter, s, is Submit Answe Tries 0/10 (c) The effective height (m) of the stack is
