A double nozzle lying in a horizontal x-y plane discharges water into the atmosphere at a rate of 0.5 m3 /s. Assume the water speed in jets A (10 cm in diameter) and B (12 cm in diameter) are the same. The pipe is 30 cm in diameter. Find the force acting on the flange bolts required to hold the nozzle in place.

The force is F= 46.25kN

Explanation:

The diagram for this question is shown on the first uploaded image

At Equilibrium the summation of the of force on the vertical axis is zero

i.e $\sum F_y =0$

=> $F_y sin \ 60^o =\rho Q (v_2 -v_1 cos \ 30^o)$

v_2 is the is the speed of water at the nozzle which can be mathematically evaluated as

$v_2 = \frac{R}{A_n}$

substituting 0.5m^3/s for R and $\frac{\pi}{4}(12*\frac{1m}{100} )^2$ for A_n

$v_2 = \frac{0.5}{\frac{\pi}{4} * (12*\frac{1}{100} )^2 }$

= 44.23 m/s

v_1 is the is the speed of water at the pipe which can be mathematically evaluated as

$v_1 = \frac{R}{A_p}$

substituting 0.5m^3/s for R and $\frac{\pi}{4}(30*\frac{1m}{100} )^2$ for A_p

$v_1 = \frac{0.5}{\frac{\pi}{4} * (30*\frac{1}{100} )^2 }$

= 7.07 m/s

$\rho$ is he density of water with value $\rho =1000 kg /m^3$

Substituting values into the equation above

F_ysin 60^o = 1000 (0.5) (44.23 -7.07 cos 30)

= 21.99kN

At Equilibrium the summation of the of force on the horizontal axis is zero

i.e $\sum F_x =0$

=> $F_y sin \ 30^o =\rho Q (v_2 -v_1 sin \ 30^o)$

Since The speed at both A and B nozzle are the same then v_2 remains the same

Substituting values

F_x sin30^o =1000 (0.5) (44.23 - 7.07*sin30)

=> F_x = 40.69kN

Hence the force acting on the flange bolts required to hold the nozzle in place is

$F = \sqrt{F_x^2 + F_y^2}$

$= \sqrt{40.69 ^2 + 21.99^2}$

F= 46.25kN

A double nozzle lying in a horizontal x-y plane discharges water into the atmosphere at a rate of 0.

Answer from: Quest

Make them both to where they have the denominator of 18that makes 3/2 equal 27/18 and 1/9 equal 2/18so now you have 27/18x+5=2/18subtract 5 from the other sideso now you have 27/18x+2/18-5then subtract 2/18 from 27/18 to get 25/18x=-5then divide 25/18 by -5 and your answer will be -5/18
