Question

How well does the theoretical model predict the measured force for the symmetric and asymmetric impact surfaces?

Answer 1

Answer:

Explanation:

1) First step would be determining the measured force through your experiment for the Reaction force of the both the surfaces on the jet of fluid stream. The value would be R_actual.

2) Second step is to compute the Reaction force by the theoretical model which takes an assumption of no kinetic energy loss from a jet of fluid stream impinging on to the surfaces i.e the velocity before and after impact is the same. This value would be R_theoratical.

3) Step Three would be to compare the actual and theoretical values of Reaction forces exerted by the surfaces by the following formula:

         % Difference = [ ( R_actual - R_theoratical ) / R_actual ] * 100

4) The standard followed is that a theoretical model must predicts within 10% uncertainty about the actual value obtained from experiment.

5) If the difference is greater than 10% it means that the assumption of no Kinetic Energy Losses was not feasible and should be included in the model for accuracy.
