Stagnation Pressure Solution

STEP 0: Pre-Calculation Summary

Formula Used

Stagnation Pressure = 2*Dynamic Pressure*(cos(Newtonian angle))^2+Free Stream Pressure
p' = 2*P_dynamic*(cos(Φ))^2+p_∞
This formula uses 1 Functions, 4 Variables

Functions Used

cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)

Variables Used

Stagnation Pressure - (Measured in Pascal) - Stagnation Pressure is the pressure at the stagnation temperature during the process of ramming.
Dynamic Pressure - (Measured in Pascal) - Dynamic Pressure is simply a convenient name for the quantity which represents the decrease in the pressure due to the velocity of the fluid.
Newtonian angle - (Measured in Radian) - Newtonian angle is the angle between the normal to the surface and the freestream.
Free Stream Pressure - (Measured in Pascal) - Free Stream Pressure is the pressure of fluid that hasn't encountered any disturbance.

STEP 1: Convert Input(s) to Base Unit

Dynamic Pressure: 12.56 Pascal --> 12.56 Pascal No Conversion Required
Newtonian angle: 56 Radian --> 56 Radian No Conversion Required
Free Stream Pressure: 7.9 Pascal --> 7.9 Pascal No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

p' = 2*P_dynamic*(cos(Φ))^2+p_∞ --> 2*12.56*(cos(56))^2+7.9

Evaluating ... ...
