(b) If the hose is attached to a nozzle with a diameter of 0.750cm, what is the speed of water in the nozzle?
m/s
(c) Is the number of kilograms per second flowing through thenozzle greater than, less than, or equal to 2.77 kg/s?

Explanation / Answer
(a) m /t = A v speed (v) = m / t * 1/ A = m / t * ( 4/ D2 ) = 2.77 * ( 4 / 1000 * 3.14 * (0.025)2) = 5.645 m/ s (b) We have: A1 v1 = A2 v2 In terms of Diameter : v2 = (D1 / D2 )2 * v1 = ( 2.50 / 0.750)2 * 5.645 = 62.72 m /s (c) It is Equal. Hope this helps u!Related Questions
