liquid-jet pump equations The liquid jet pump is described in terms of the four flow processes by Equations (1), (3), (5), and (7). The term gfs = pGs QGJp1Q1. For isothermal flow, gfs = 144Psfs/RTsp1. For air, with R = 1716 ft lb/slug °R, and water, p1 = 1.94 slugs/ft3 and gfs = .0432Psfs/Ts. In SI, R = 286.92 mN/kg °K, p1 = 1000 kg/m3, and gfs = .00348Psf JTs, with Ps in kN/m2, and Ts in °K. The R and/or p1 values must of course be replaced for fluids other than water and air.

In the LJGL pump, the secondary flow is a bubbly mixture of a gas in a liquid. Compressible flow phenomena must be considered because the velocity of sound is quite low in bubbly fluids. For example, the velocity of sound in a 50/50 uniform mixture of air in water is about 70 ft/s (21.3 m/s), far below sonic velocities in air (1100 ft/s or 335 m/s) or water (5000 ft/s or 1524 m/s).

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable.
