Homework Statement
q1.
a)Explain the terms stream-tube.
b)State the equation of continutity along a stream-tube for an incomperssible fluid.
c)A hosepipe with an internal cross sectional area A1 has at its end a nozzle with a hole whose cross-sectional area is A2 (A2<A1). If the speed of the water as it emerges from the nozzle is vo, determine its speed in the hosepipe. Also, determine the excess pressure inside the hosepipe, which is horizontal.
Homework Equations
p + pgh + 1/2 pv^2
The Attempt at a Solution
a) A thin bundle of adjacent streamlines forming a stream tube.
b) equation of continutity :
v1*d*A1 = v2*d*A2
for an incompressible fluid.
c)
p + Pgh + 1/2 Pv^2
v1*d*A1 = v2*d*A2
V1= vo
