a force F of 2n is applied to a plunger with a crossectional area of 2.5*10^-5m, the area of the needle is 1*10^-8 sq meters, the static pressure every where is 1 atmopshere, it is horizontal, and it is filled with water. what is the velocity of the water exiting. please help.(adsbygoogle = window.adsbygoogle || []).push({});

i know that the equation should reduce to this:

f=p*a

2n=p*a

2n=p*2.5*10^-5

pp1=80000

101325+80000=181325pa=P1

pp2=2/1*10^-8=200000000

pp2+101325=p2=200101325

P1+1/2*d*v1^2+dgh1=P2+1/2*d*v2^2+dgh2

H1=h2

P1+1/2*d*v1^2=P2+1/2*d*v2^2

is this right, and if so, how do i get v, if not what is wrong
