Question

Steady flow (2) 2 ft Dia = 0.12ft 0(1) Gage pressure is zero 3 ft Dia = 0.1 ft Free Jet Given: Gage pressure at point (1) is zero Non-viscous flow Ywater = 62.4 Lbf/ft3 Find: Pressure in Lbf/ft? at point (2) Flow rate in ft/sec at point (2)

Answer 1

Solution in Date given Steady flow + brooge pressure of poiss +(?)==0 Mon viscous flow (ie. No luss) & Ywater = 68.4 lb/ft3 24 Pi=0 guage pressure (1) for pressure at section et Assuming datum as exit of 3 ft force fet Dia = 0.1 ft - Datum free get ► apply bernaeli eluealice between point » 4 2 Pe Vi +za 2 Ve eg Pi Pg t + Zi ag eg por {a A = Az, hence ☆ vi = ve }, eg = you + 5 7 0+3 Pe Yeu - =) 2 PE 62. guage pressure =) ( Pq = -124.8 l belfte o PR --104.8 +916-22 =1991.42065/absolute prasaune.

(2) for flow apply Bernaldi equation between point 40 - assuming atmospheric pressure al reference pressure. > pressure at section : 0 & P3 = 0 fal atmospheric pressure is taken as refference? hence 2 2 vi Vz PI Yw + + Zia P, Yw + + Zz 29 29 دران o t vi? 2 +3 = 0 + V3 +0 Jo eg Continul muity eluation A.
