Question

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?

Answer 1

Answer:

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
