ρ = (.5 psi)(144 in2/ft2) / (1716)(609.7)SteamKing said:
Is P = 0.5 psi absolute or gage reading?reddawg said:
Yes, I agree with those units. And P is absolute pressure I think.SteamKing said:
If P is absolute pressure, then the tank cannot exhaust to atmosphere, since the pressure there > the supposed pressure inside the tank.reddawg said:
The energy equation involving head loss is a fundamental equation in fluid mechanics that governs the transfer of energy within a fluid system. It states that the total energy at any point in the system is equal to the sum of the kinetic energy, potential energy, and the energy lost due to friction or head loss.
Head loss is calculated using the Darcy-Weisbach equation, which relates the head loss to the friction factor, pipe length, diameter, and flow rate. The equation can also be simplified for certain flow regimes, such as laminar or turbulent flow.
Head loss in a fluid system can be caused by a variety of factors, including pipe roughness, changes in elevation, flow rate, and fluid viscosity. Other factors such as fittings, bends, and valves can also contribute to head loss.
Head loss can significantly affect the performance of a fluid system by decreasing the total energy available for the fluid to flow through the system. This can result in decreased flow rates, increased pumping power requirements, and reduced efficiency of the system.
Head loss can be minimized by using smoother pipes, minimizing the number of fittings and bends, and reducing the flow rate. Additionally, choosing the appropriate pipe diameter, fluid viscosity, and flow regime can also help to reduce head loss in a fluid system.
