HI. I'm confused in how to find pressure in horizontal Pipe theoretical. Pipe having 90mm dia and water flowing through 3m/s. If I'm insert one plate in pipe having surface area 'x', then how much pressure acting on the surface of plate by water? please explain me.

The pressure acting on the surface of the plate will depend on the type of fluid in the pipe, the density of the fluid, and the height of the fluid upstream of the plate. To calculate the pressure, you would use the equation for hydrostatic pressure: P = ρgh, where ρ is the density of the fluid, g is the acceleration due to gravity, and h is the height of the fluid upstream of the plate.

## 1. How is fluid pressure calculated in a flowing pipe?

Fluid pressure in a flowing pipe can be calculated using the Bernoulli's equation, which takes into account the velocity, elevation, and density of the fluid. It states that the total energy of the fluid remains constant. Therefore, the pressure at any point in the pipe can be calculated by measuring the velocity of the fluid, the elevation of the point, and the density of the fluid.

## 2. What are the units used to measure fluid pressure?

Fluid pressure is typically measured in units of force per unit area, such as pounds per square inch (psi), newtons per square meter (N/m²), or pascals (Pa). These units represent the amount of force exerted by the fluid on a given area.

## 3. How does the diameter of a pipe affect fluid pressure?

The diameter of a pipe has a direct impact on the fluid pressure. As the diameter of a pipe decreases, the velocity of the fluid increases, resulting in a decrease in pressure. This is known as the Venturi effect. Conversely, as the diameter of a pipe increases, the velocity of the fluid decreases, resulting in an increase in pressure.

## 4. Can fluid pressure in a pipe be increased?

Yes, fluid pressure in a pipe can be increased by either increasing the velocity of the fluid or decreasing the diameter of the pipe. This can be achieved by using a pump to increase the flow rate of the fluid or by using a nozzle to decrease the diameter of the pipe. However, it is important to note that increasing the pressure too much can cause damage to the pipe and other components.

## 5. How does the type of fluid affect fluid pressure in a pipe?

The type of fluid being used can have a significant impact on the fluid pressure in a pipe. For example, a denser fluid will exert more pressure on the walls of the pipe compared to a less dense fluid. Similarly, a more viscous fluid will experience more resistance and therefore a decrease in pressure as it flows through a pipe. Additionally, the temperature and state (liquid or gas) of the fluid can also affect its pressure and flow behavior in a pipe.
