In addition, fluid is lost out of a hole at 9. estimated at a rate of 0.1 m'is. The avcrage speeds at sections @ and 3 are V =5 mis and V3= 12 mis, respectively. Find the velocity at scction 30 Given: Steady flow of water through the device. A = 0.2 m A: = 0.2m A, = G,15 m V = 5m/s V, = 12 m/s p= 999 kg/m Volume flow rate at -0.1 m's Find: Velocity at section .
