A level pipe contains a nonviscous, incompressible fluid with a density 1200 kg/m3 that is flowing steadily. At one position within the pipe, the pressure is 300 kPa and the speed of the flow is 20.0 m/s. At another position, the pressure is 200 kPa. What is the speed of the flow at this second position?

V2 = 23.8m/s

Explanation:

as we know That,

p1 / (r*g) + (v1^2) / 2*g = p2 / (r*g) + (v2^2) / 2*g

p1=300kPa=300000Pa

p2=200kPa=200000Pa

r=1200kG/m^3

v1 = 20 m/s

250+200 = 166.66 + (v2^2) / 2

v2 = (450-166.66) * 2

v2^2 = 566.68

v2=23.8m/s

Your answer is : V2 = 23.8m/s
