If the peak pressure at transfer is 15,000 psispec and there was a twenty percent rise in viscosity, what would the new peak pressure at transfer potentially be?
Understand the Problem
The question asks to calculate the new peak pressure given an initial peak pressure and a percentage increase in viscosity. It seems like you need to understand the relationship between viscosity and pressure to determine the new peak pressure after the viscosity increases by twenty percent.
Answer
18,000 psispec
Answer for screen readers
18,000 psispec
Steps to Solve
-
Calculate the increase in peak pressure The problem states that the peak pressure increases proportionally with the viscosity. We need to calculate 20% of the initial peak pressure. $$ \text{Increase} = 0.20 \times 15000 $$
-
Determine the increase in peak pressure $$ \text{Increase} = 3000 \text{ psispec} $$
-
Calculate the new transferred peak pressure Add the increase in peak pressure to the original peak pressure. $$ \text{New peak pressure} = 15000 + 3000 $$
-
Determine the new transferred peak pressure $$ \text{New peak pressure} = 18000 \text{ psispec} $$
18,000 psispec
More Information
The new peak pressure is calculated by adding the increase in pressure due to the increase in viscosity to the initial peak pressure.
Tips
A common mistake is to calculate 20% of the initial peak pressure and then stop, failing to add this increase to the original pressure to find the new peak pressure. Another mistake might be to misunderstand the problem and subtract the increase instead of adding it.
