Question

A 3-m long water pipe with the cross-sectional area 20 cm2 inclined at 30 degrees to the wall is connected to a system under the pressure P1 at the top end. The water flows here with the speed of v1. At the bottom end it is joined with a horizontal pipe of the cross-sectional area 5 cm2. The water flows out of the horizontal pipe at a speed of 10 m/s. Find 
a) The rate of flow in L/s (1L-10^-3 m3, 1 m3 = 10^6 cm3)
b) The speed v1
c) The pressure P1
