A nozzle that discharges a 60-mm-diameter water jet into the air is on the right end of a horizontal 120-mm- diameter pipe. In the line, the water has a velocity of 4 m/s and a gage pressure of 400 kPa. Find the magnitude and direction of the resultant axial force the water exerts on the nozzle and the head loss in the nozzle.
For the system shown below, calculate the vertical distance (in meters) between the surfaces of the two reservoirs when water at 10°C flows from A to B at the rate of 0.03 m3/s. The elbows are standard. The inlet is inward projecting, and the exit is square edged. The total length of the 4-in pipe is 94 m. For the 6-in pipe it is 274 m.
. Water flows at 6 gal/min through a small circular hole in the bottom of a large tank.
Assuming the water in the tank approaches the hole radially, find the velocity in the tank
at 2, 4 and 8 in from the hole.
