Lab 7: Impact of a Jet: 30, 60, 90,120 & 180-degree deflector (Theory and Demo)

[@zhraaaly2308]

Which slope is more efficient at the angle (90, 120, 180) degrees and why?

[@MohammadShafinulHaque]

Zhraa if you consider the force equation (see around 4:00 min); the force depends on the theta for a fixed flow velocity, thus the lower the value of theta (in degree) the higher the value of cos(theta) that will result higher value of force F. Since the 180 deflector will have zero theta value, will have highest force thus most efficient.

Good efforts

you are welcome.

How can I calculate the expremental force
I don’t understand

[@MohammadShafinulHaque]

You need to record the counter balance mass add on the top and use the F=mg Newton 2nd law to calculate the experimental force.

hello..
can I get dimensions of cylinder only
(height and width)
thanks

Thank you, this is a great video. Why does the 30 degree deflector behave differently to the others?

[@MohammadShafinulHaque]

What differences you are taking about? Differences in flow direction?

[@falcond214]

It is not clear how well the experiment has supported the theory presented in , also there is nothing about the
significance of the experimental error/uncertainty in that regard

Hello sir what are the assumption made during the experiment

[@MohammadShafinulHaque]

It is assumed that "The magnitude of the flow velocity does not change (energy equation), only the direction of the flow changes."
