At a given point in a flow, T = 300 K, p = 1.2 atm, and V = 250 m/s. Atthis point, calculate the corresponding values of p0, T0, p∗, T ∗, and M∗.
The modern engineering design and operation of fluid flow processes were developed using the Bernoulli’s principle. The fluid transport conditions, such as flow velocity and pressure in z-direction, can be related using the Bernoulli equation, expressed as
ρ V2/2 + ρ g z + P = constant (Q1)
1. Explain the physical meaning of Bernoulli equation and list any assumptions to
obtain Equation (Q1).
2. Explain the Venturi flow meter developed using the Bernoulli equation.
4. Consider a wide liquid film of constant thickness h flowing steadily due to
gravity down an inclined plane at angle 0. AS shown in below figure. The
atmosphere exerts constant pressure and negligible shear on the free surface.
