State whether the following statements are true or false St

State whether the following statements are true or false. () Stoke\'s law is valid if medium is infinite only. () The Gibson and Jacobs formula is used to correct the velocity when measuring the viscosity to take into consideration the effect of the wall and end of the tube. () The Orifice -meter is an area meter where the pressure drop is nearly constant, and the area through which the flow varies with the flow rate. () The performance of a centrifugal pump is represented by its characteristic curve. () In Pumps connected in series, practically; the head will be slightly lower than the double because of the head losses that increase with the square of the flow rate. () (Qt= Ql= Q2=.......= Qn), (H = H1+ H2+.........+ Hn) these two equations refer to pumps connected in series and parallel, respectively. () In the Impact of Jet Experiment, as the flow Rate Q Increases; the force in both flat Plate and hemispherical cup decreases. () The outlet angle beta of the jet is at 180degree in respect to the inlet direction. () The jet outlet speed from the nozzle is measured from the jet flow rate and area of the object. () The resultant hydrostatic force applied on a submerged surface is equal to the static force only.

Solution

1. False ---As this law can used for known size/volume of fluid.

3. False --We may have Reasonable pressure drop.

4. True---These Charastaristics are drawn in the form of Cureves.

5. True---As there is less loss due to friction.

6. False--Its exactly reversed as that of stated one.

7.False---It may increase in most of times.

8.False....it can vary.

9.True.

10. True.
