A plate of area 2m^(2) is made to move h...

A plate of area `2m^(2)` is made to move horizontally with a speed of `2m//s` by applying a horizontal tangential force over the free surface of a liquid. If the depth of the liquid is 1m and the liquid in contact with the bed is stationary. Coefficient of viscosity of liquid is `0.01` poise. Find the tangential force needed to move the plate.

AI Generated Solution

To find the tangential force needed to move the plate, we can use the formula for viscous force derived from Newton's law of viscosity. Here are the steps to solve the problem: ### Step-by-Step Solution: 1. **Identify the Given Data:** - Area of the plate, \( A = 2 \, m^2 \) - Speed of the plate, \( v = 2 \, m/s \) - Depth of the liquid, \( h = 1 \, m \) ...
