A fireman standing on a 5.2 m high ladder operates a water hose with a round nozzle of diameter 1.43 inch. The lower end of the hose (5.2 m below the nozzle) is connected to the pump outlet of diameter 2.33 inch. The gauge pressure of the water at the pump is
P(gauge) =P(abs) −P pump pump
atm= 26.2 PSI = 180.643 kPa .
Calculate the speed of the water jet emerg- ing from the nozzle. Assume that water is an incompressible liquid of density 1000 kg/m3 and negligible viscosity. The acceleration of gravity is 9.8 m/s2 .
Answer in units of m/s.

A fireman climbs a 9 m high ladder carrying a 5.9999 in diameter hose that has a 1.2 in diameter nozzle. The pump has an absolute pressure of 4 atm . What is the water velocity from the nozzle? Assume that water is incompressible, its density is 1000 kg/m3 , and 1 inch = 0.0254 m. The acceleration of gravity is 9.8 m/s 2 and 1 atm = 1.01

Problem 6.077 Incorrect. A fireman is soaking a home that is dangerously close to a burning building. To prevent water damage to the inside of the neighboring home, he throttles down his flow rate so that it will not break windows. Assuming the typical window should be able to withstand a force up to 30 lbf, what is the largest volumetric flow rate he should allow (gal/min.), given an 10 inch diameter (D1) firehose discharging through a nozzle with 3-inch...

8-C) As shown below water is pumped and sprayed through a nozzle into the atmosphere at 20 m/s at an elevation 10 m above the reservoir surface. The mass flow rate is 40 kg/s and the volumetric flow rate is 0.040 m3/s. The large diameter inlet pipe total length is 50 m. The pump effidency is 65%. The longer smaller diameter pipe leaving the pump is 200 m in total length. The pipes have different diameters as indicated below. The...

Problem 1. Water flows from a large tank through a smooth pipe of length 80 m. Both the tank free surface and jet exit are exposed to the atmosphere. Take the density of water p = 1000 kg/m3, dynamic viscosity of water u = 0.001 kg/m.s, atmospheric pressure = 100 kPa, and gravity = 9.8 m/s2. Calculate the volumetric flow rate through the pipe. Neglect entrance losses to the pipe. Hint: Consider the inlet and outlet sections of the pipe...
