To determine The velocity of air just above the points A , B , C , and D . Explanation Write an expression of Bernoulli’s equation . p o + 1 2 V o 2 + g z o = p i + 1 2 V i 2 + g z i (I) Here, acceleration due to gravity is g , density of air is ρ , the outlet pressure, outlet velocity, outlet datum are p o , V o , and z o , and number of pressure, velocity, and datum at various points are p i , V i , and z i . Substitute 0 for z o and 0 for z i in Equation (I). p o ρ + 1 2 V o 2 = p i ρ + 1 2 V i 2 V i = 2 ( p o − p i ) ρ + V o 2 (II) Substitute 13.2 psi for p o , 0.002 slug / ft 3 for ρ , and 100 mph for V o in Equation (II). V i = 2 ( 13.2 psi − p i ) 0.002 slug / ft 3 + ( 100 mph ) 2 = 2 ( 13.2 − p i ) × lb in . 2 × 144 in . 2 ft 2 0.002 slug / ft 3 × ( lb ⋅ sec 2 slug ⋅ ft ) + 10000 ( mph ) 2 = 66600 ( 13.2 − p i ) + 10000 mph (III) Write the expression to determine the velocity at point A ( V A ) using Equation (III). V A = 66600 ( 13.2 − p A ) + 10000 mph (IV) Here, the pressure at point A is p A
