According to equation of continuity,

Water flows from pipe diameter $200\text{ mm}$ to $100\text{ mm}$. If velocity in larger pipe is $2\text{ m/s}$, find velocity in smaller pipe.

Given the variables: velocity (V), density ($\rho$), viscosity ($\mu$), and characteristic length (L), how many dimensionless groups can be formed?

In a horizontal pipe, velocity doubles. Pressure gets

For a laminar boundary layer developing over a flat plate, the displacement thickness is defined as: $\delta^* = \int_0^\delta \left(1 - \frac{u}{\text{U}_\infty}\right) dy$. Physically, $\delta^*$ represents

For Inlet diameter $>$ Outlet diameter the Velocity and pressure along the flow will be as

Drag force $F$ depends on density $\rho$, velocity $V$, and diameter $D$: $F = k \rho^a V^b D^c$. Find exponents $a, b, c$.
