Water is discharged at a flow rate of 0.3m3/s from a narrow slot in a 200-mm-diameter pipe. The resulting horizontal two dimensional jet is 1 m long and 20 mm thick, but of non-uniform velocity; the velocity at location 2 is twice that at location 1. The pressure at the inlet section is 50 kPa (gage). Calculate (a) the velocity in the pipe and at locations 1 and 2 and (b) the forces required at the coupling to hold the spray pipe in place. Neglect the mass of the pipe and the water it contains.
