Here is how the Newtonian Dynamic Pressure equation looks like.

12.05 = 0.5 \cdot (32 - 7.9)

12.05Pa = 0.5 \cdot (32Pa - 7.9Pa)

12.05 = 0.5 \cdot (32 - 7.9)

Newtonian Dynamic Pressure Solution

Follow our step by step solution on how to calculate Newtonian Dynamic Pressure?

FIRST Step Consider the formula

P dynamic = 0.5 \cdot (p' - p ∞)

Next Step Substitute values of Variables

∴

P dynamic = 0.5 \cdot (32Pa - 7.9Pa)

Next Step Prepare to Evaluate

∴

P dynamic = 0.5 \cdot (32 - 7.9)

LAST Step Evaluate

∴

P dynamic = 12.05Pa

How to Evaluate Newtonian Dynamic Pressure?

Newtonian Dynamic Pressure evaluator uses Dynamic Pressure = 0.5*(Stagnation Pressure-Free Stream Pressure) to evaluate the Dynamic Pressure, Newtonian Dynamic Pressure is defined as half of the difference between stagnation pressure and static pressure of the freestream flow. Dynamic Pressure is denoted by P_dynamic symbol.
