Question

The pressure in a hydraulic line increases from 40 psi to 75 psi. What is the percent increase in pressure?

Answer 1

Get the difference of the pressure in hydraulic line.

`75\text{ psi}-40\text{ psi}=35\text{ psi}`

Next, divide the difference from the original psi, and multiply by 100%

`\begin{gathered} 35\text{ psi}/40\text{ psi}=0.875 \\ 0.875*100\%=87.5\% \end{gathered}`

Therefore, the increase in pressure is 87.5%.
