Question

What is the difference between

• Static pressure
• Stagnation pressure
• Dynamic pressure?

Make a sketch and explain! What is the relation between the three pressures? How can you calculate the dynamic pressure?

Answer 1

Solution Pressure Gauge .P Bernoulli's equ - Constant P + 2 + z = P= static pressure The pressure that would be measured by an instrument that is static wort the fluid. That is "static Pressure when a flowing fluid is decelerated to 200 speed by a a friction less Process Ci-e tube the pressure measured at that Stagnation point is called in pressor 1 1 0 Po thor = f to 2 I 2 Pot S Vo TP.17 CS Scanned with CamScanner
