In the water-jet pump, the overpressure at the supply of the working fluid (water) was p1, kgf / cm2 at a flow rate of 1, m / s. Determine the overpressure in the nozzle jet if the velocity in it was 2, m / s (use the Bernoulli equation, neglecting the pressure loss).
It is set: excess pressure of the working fluid (water) p1 = 6 kgf / cm2 = = 6 * 105 Pa; flow velocity 1 = 1.5 m / s; flow velocity 2 = 21 m / s.
Define: overpressure p2.
