Question

A jet pf 5 cm diameete moving at a velocity of 30 on symmetrical curved fixed planes at cente.Find the force exerted by the jet in the direction of jet and normal to jet when jet is deflected through 130 degree at outlet of curved surface​

Answer 1

Answer:

Step-by-step explanation:

Given:

i) Diameter of jet, d = 50mm = 0.05m

ii) Area, a=π4(0.05)2=0.001963m2

iii) Velocity, v = 40m/s

∴ To find θ, use equation

180−θ = given angle

180−θ=120

∴,θ=180−120=60∘

∴Fx=ρav2[1+cosθ]

Fx=1000×0.001963×402×[1+cos60∘]

Fx=4711.5N
