The turbine shown in fig. p5.114 develops 100 hp when the flowrate of water is 20 ft3 /s. if all losses are negligible, determine (a) the elevation h, (b) the pressure difference across the turbine, and (c) the flowrate expected if the turbine were removed. gerhart, philip m.; gerhart, andrew l.; hochstein, john i.. munson, young and okiishi's fundamentals of fluid mechanics, 8th edition (page 273). wiley. kindle edition.

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
