In a force pump, a force of 50N is applied on a Piston of diameter 0.4m during the down stroke. Find the pressure exerted on the water by the Piston
We can use the formula:
Pressure = Force / Area
Where the force is 50N and the area is the area of the piston, which is:
Area = π(0.4/2)^2 = 0.126m^2
Substituting these values into the formula, we get:
Pressure = 50N / 0.126m^2 = 396.83 Pa
Therefore, the pressure exerted on the water by the piston is approximately 396.83 Pa.
To find the pressure exerted on the water by the piston, we need to use the formula for pressure:
Pressure = Force / Area
In this case, the force applied on the piston is 50N, and we need to find the area of the piston.
The area of a circle is given by the formula:
Area = π * (radius)^2
The diameter of the piston is given as 0.4m. To find the radius, we can divide the diameter by 2:
Radius = 0.4m / 2 = 0.2m
Now we can calculate the area:
Area = π * (0.2m)^2
Area = π * 0.04m^2
Area = 0.04π m^2
Now we can calculate the pressure:
Pressure = Force / Area
Pressure = 50N / 0.04π m^2
Pressure ≈ 1256.64 N/m^2
Therefore, the pressure exerted on the water by the piston is approximately 1256.64 N/m^2.
