A fire hose has an inside diameter of 6.40 cm. Suppose such a hose carries a flow of 40.0 L/s starting at a gauge pressure of 1.62×106N/m2 . The hose goes 10.0 m up a ladder to a nozzle having an inside diameter of 3.00 cm. Calculate the Reynolds numbers for flow in the fire hose and nozzle to show that the flow in each must be turbulent.

Fire hoses used in major structural fires have an inside diameter of 6.40 cm. Suppose such a hose carries an inital flow of 40.0 L/s at ground level, starting at a gauge pressure of 1.62 x 106 N/m2. The hose rises up 10.0 m along a ladder to a nozzle having an inside diamter of 3.00 cm. (Hint use Bernoulliʻs equation) 1)Draw a diagram of what is happening? 2)What is the speed at v1 and v2 in m/s? 3)What is...

. A steam main (outside diameter of 16.8 cm and inside diameter of 15.4 cm) is covered with 5-cm of high temperature insulation (k = 0.095 W/m. K) and 3.8 cm of lower temperature insulation (k = 0.07W/m. K). Calculate the heat loss from 150 m pipe assuming that inner and outer surface temperatures of the insulation are 450 and 30 °C, respectively. Also determine the temperature at the interface between two layers of insulation (10 points).

A water hose 2.85 cm in diameter is used by a gardener to fill a 28.0-liter bucket. (One liter = 1,000 cm3.) The gardener notices that it takes 1.00 min to fill the bucket. A nozzle with an opening of cross-sectional area 0.500 cm2 is then attached to the hose. The nozzle is held so that water is projected horizontally from a point 1.00 m above the ground. Over what horizontal distance can the water be projected? 4.33 m *CORRECT*...
