Water flowing out of a horizontal pipe emerges through a noz

Water flowing out of a horizontal pipe emerges through a nozzle. The radius of the pipe is 2.5 cm, and the radius of the nozzle is 0.46 cm. The speed of the water in the pipe is 0.58 m/s. Treat the water as an ideal fluid, and determine the absolute pressure of the water in the pipe.A pipe is horizontal and carries oil that has a viscosity of 0.14 Pa s. The volume flow rate of the oil is 5.6 × 10-5 m3/s. The length of the pipe is 37 m, and its radius is 0.58 cm. At the output end of the pipe the pressure is atmospheric pressure. What is the absolute pressure at the input end?
