Question

The formula of speed and pressure

Answer 1

Answer:

⬇️⬇️⬇️⬇️⬇️⬇️⬇️

• Pressure is inversely proportional to velocity, so we have lower pressure at the exit of the nozzle. But as per definition of pressure, P=F/A, i.e., pressure is inversely proportional to the area which contradicts the above explanation on basis of continuity and Bernoulli equation.

• In Science pressure is equal to the net amount of force acting per unit area. Dimensional Formulae of force is M1L1T-2 and of area is L2. Therefore Pressure's dimension can be obtained by calculating Force by Area. Dimensional formula of pressure difference is M1L-1T-2.

CORRECT FORMULAS

• $\sf\red{Speed =>\frac{Distance} { Time}}$
• $\sf\orange{Pressure =>\frac{Thrust} {Area}}$

☞KNOW MORE-:

• $\sf\blue{Distance =>Speed × Time}$
• $\sf\green{Time =>\frac{Distance}{Speed}}$

1. THRUST IS PERPENDICULAR FORCE .
2. FORCE IS PULL OR PUSH .
