What is the pressure difference Δp = p(inside)-p(outside)? Use 1.28 kg/m³ for the density of air. Treat the air as an ideal fluid obeying Bernoulli's equation.
Answer : The pressure difference will be,
Step-by-step explanation :
As we are given:
Speed = 150 km/h = 41.66 m/s
Density =
Area = A = 7.00 m × 12.0 m
Formula used :
Now put all the given values in this formula, we get:
Thus, the pressure difference will be,
