Question

Calculate the thrust required in newton to produce a pressure of 48,000 Pa on an area of 1000 cm2

Answer 1

4800N

Step-by-step explanation:

This question involves the pressure formula.

We know that: Pressure = Force (thrust in this case) ÷ Area

Note that area is in

`{m}^(2)`

First, we have to convert the area first.

We know that:

`1 {cm}^(2) = (0.01m) * (0.01m) \\ = 0.0001 {m}^(2)`

Therefore,

`1000 {cm}^(2) = 0.0001 * 1000 = 0.1 {m}^(2)`

Therefore we can now use the pressure formula to solve for F, the thrust.

P = F ÷ A

48000 = F ÷ 0.1

F = 48000 × 0.1 = 4800 N
