You are expected to find it from the depth of the tank.foo9008 said:
i am going to use this equation to solve this question , where z = 10 m what is the pressure at ENTRANCE ? it's not givenbilly_joule said:
To calculate entrance pressure in pipes, you can use the Bernoulli's equation, which takes into account the fluid velocity, density, and height difference between the entrance and exit of the pipe. You can also use the Darcy-Weisbach equation, which takes into account factors such as pipe roughness and friction losses.
Static entrance pressure is the pressure exerted by a fluid at rest at the entrance of a pipe. Dynamic entrance pressure, on the other hand, is the pressure exerted by a moving fluid at the entrance of a pipe. It takes into account the fluid's velocity and kinetic energy.
The diameter of a pipe does not directly affect the entrance pressure. However, a smaller pipe diameter may result in higher velocity and friction losses, which can impact the overall entrance pressure in the pipe.
Entrance pressure in pipes can be affected by various factors such as fluid density, velocity, viscosity, pipe diameter, pipe roughness, and any changes in elevation or direction of the pipe. Other external factors such as temperature and pressure can also play a role.
To solve for unknown entrance pressure in a pipe system, you can use the equations mentioned earlier (Bernoulli's equation or Darcy-Weisbach equation) and plug in the known values for fluid properties and pipe characteristics. You may also need to use additional equations to account for losses due to fittings, valves, or other components in the pipe system.
