Question

A pipe system carries water from a reservoir and discharges it as a free jet, as shown. The system consists of piping made from 200-mm diameter commercial steel pipe with two 90 deg elbows with K -0.4m and an inlet minor loss Kl = 0.05 1) (4 pts) Assuming ideal fluid model within the reservoir, show that pressure at point A is VA PA = Pamb +(30 m) - and draw on the diagram the streamline you used. TOT

Answer 1

501) 16 coe 1) coe assume can fluid model ideal then neglect friction minor losses losses and in flow we Know bernouli's Equation between two points of flow Put + Zi + + Z₂. Р 29 sg 29 16 we apply bernouli's Eruation between reservoir top and at a flow point Aman so Reservoirs is at atmosphere open pressure will be atmospheric pressure and velocity is zero. PA P9 + Pamb 89 + ZA 29 29 Pamb 89 + z, ZA 29 nator PA = Pamb + 8g (Z - A) between 89 r. and potential head differece reservoir and point A (2,-2) = SA 30 m.
