At one end the hose has inside diameter of d1= 5cm ad is connectedto high pressure water reservoir at P1=300psi. At the other end is nozzle withdiameter d2=3cm that is exposed to atmospheric pressure P2=1atm.To a good approximation, flowing water in this process can be modelled ashaving a constant temperature and constant mass density =1g/cc.
