A valve in the cylinder shown in Fig. $\mathrm{P} 2.47$ has a cross-sectional area of $11 \mathrm{cm}^{2}$ with a pressure of $735 \mathrm{kPa}$ inside the cylinder and $99 \mathrm{kPa}$ outside. How large a force is needed to open the valve?

Step 1
Step 1: Calculate the net force required to open the valve using the formula: \[ \text{Net Force} = (\text{Inside Pressure} - \text{Outside Pressure}) \times \text{Area of the valve} \] Show more…

A valve in a cylinder has a cross-sectional area of 2 in $^{2}$ with a pressure of 100 psia inside the cylinder and 14.7 psia outside. How large a force is needed to open the valve?
A piston having a cross-sectional area of $0.07 \mathrm{m}^{2}$ is located in a cylinder containing water as shown in Fig. $\mathrm{P} 2.73 .$ An open U-tube manometer is connected to the cylinder as shown. For $h_{1}=$ $60 \mathrm{mm}$ and $h=100 \mathrm{mm},$ what is the value of the applied force, $P$ acting on the piston? The weight of the piston is negligible.
