1. The horizontally lying device or fitting shown below connects three pipelines. Water (γwater = 9.81 kN/m3 ) enters the device through A with a speed VA = 8 m/s and a pressure PA = 70 kPa . Water exits through C at 9 m/s. Friction and minor head losses through the device are negligible. Note that B and C are not at atmospheric pressure. (a) Calculate the speed and flow rate of the water at B. Is the water flowing through B flowing into to the device or out of the device? (b) Calculate the pressures at B and C, PB and PC.
