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
The cross section of the hose is circular. The circumference of a circle is 2πR and the area of a circle is πR2, where R is the radius of the circle. 1 milliliter = 1 cm3. 1.If the inner diameter of the hose is 0.98 cm, and the water flows in the hose with a speed of 0.63 m/s, what is the volumetric current Q of the water flowing in the hose (in milliliters per second)? 2.If the inner diameter...
Water is flowing through a circular tube with a cross-sectional area 0.4m^2 at a rate of 8m/s. Step 1: the cross-section of the tube gradually decreases to 0.2m^2, Step 2: then the water shoots out upright from the tape (in the up vertical direction), and gains 4m in height. What is the new velocity of the water after it gains 4m in height? [save to 1 decimal places] Assume g=10m/s2; for step 1 and 2, the water is under the...
180 mm 160 mm -1.2 m- -0.9 m A shaft of solid circular cross section consisting of two segments is shown in the first part of the figure. The left-hand segment has diameter 80 mm and length 1.2 m; the right-hand segment has diameter 60 mm and length 0.9 m.

A liquid (NOT WATER) is passed through a tube with a square cross section of 0.01m x 0.01m at a Reynolds number of 2,000. The liquid has a Prandtl number of 1, a thermal conductivity of 0.2 W/mK, and a heat capacity of 4,000 J/kg*K. Simultaneously, air is blown at a speed of 20 m/s and a temperature of 25°C over the outside of the tube such that the flow is perpendicular to one of the square sides. The liquid...
The question concerns water flowing in or from a hose. The cross section of the hose is circular. The circumference of a circle is 2πR and the area of a circle is πR2, where R is the radius of the circle. 1 milliliter = 1 cm3. If the inner diameter of the hose is 1.2 cm, but you partially cover the opening of the hose leaving an open area of 0.3 cm<sup>2 </sup>at the end of the hose. The water...
