Can anyone help me with the following question? The force F exerted by a jet of water as it strikes a stationary flat plate at right angles is given by the formula : f = pπd2v2 / 4. where p: 1000kgm3 (density of water), d = 0.05m (diameter of the jet), π = 3.142 pi, F =450 force. Determine the velocity v in ms-1 that the jet will deliver the force.... having a bit of a brain fart at the moment

you've just got to re-arrange that motherfucker. Alas its been a while since i did that though im afraid

dont think he needs to do any derivations...just re-arrange it and make sure the units make sense when u have done so

id need a physics book to get that. math isnt the hardest part in there, as fractal said, the units have to fit.

4 x 450 (force) = 1000 x 3.142 x 0.0025 = 7.855 1800/7.855 = 229.153 i got 229.153 and the square root of that is 15.138 show me ur workings

hahahahaha i havnt got a fucking clue mate I just picked a number out the air awesome to know I was close-ish
