A fireman standing on a 9.1 m high ladder operates a water hose with a round nozzle of diameter 1.8 inch. The lower end of the hose (9.1 m below the nozzle) is connected to the pump outlet of diameter 3.1 inch. The gauge pressure of the water at the pump is(gauge) Plamp-P, tin 50.6 PSI 348.875 kPa (abs) pump atmCalculate the speed of the water jet emerging from the nozzle. Assume that water is an incompressible liquid of density 1000 kg/m^3 and negligible viscosity. The acceleration of gravity is 9.8 m/s^2 . Answer in units of m/s.

The speed of the water jet emerging from the nozzle is 24.21 m/s.

Explanation:

Given that,

Height = 9.1 m

Diameter =1.8 inch

Gauge pressure = 348.875 kPa

We need to calculate the speed of the water jet emerging from the nozzle

Using Bernoulli's equation

Put the value into the formula

Hence, The speed of the water jet emerging from the nozzle is 24.21 m/s.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
