figure 4.2 shows a vacuum tank with a flat circular observation window in one end. If the pressure in the tank is 0.12psia when the barometer reads 30.5in of mercury, calculate the total force on the window.
Total force on the window.
Answer to Problem 4.1PP
The required value of the force is
Explanation of Solution
Given information:
Formula used:
Calculation:
We know the standard formula to calculate pressure, i.e.:
Then,
Let us assume that the pressure in the tank is
Net pressure acting in the tank is,
From equation (a);
Then, the net force acting on the window is;
