can someone help me? Thank you. 

The open jet of water at 20°C exits a nozzle into sea-level air and strikes a stagnation tube as shown. The pressure at the centreline at section (1) is P1=140 kPa, and the diameter at (1) is D1=12 cm. The diameter of the jet is D2-4 cm. Estimate the jet velocity (V2= ? m/s). Hint: Apply Conservation of Mass as well as Bernoulli Equation between (1) and (2). Assume losses are neglected and density does not change between (1) and (2). P2 = Patm = 101350 Pa Pwater = 998 kg/m3 JI 4 cm H Water 12 cm (1) -(2)- Open jet Sea-level air V2=6.15 m/s V2=12.63 m/s V2=8.86 m/s V2=10.91 m/s
