A 12-mm diameter jet of water discharges vertically into the atmosphere. Due to surface tension the pressure inside the jet will be slightly higher than the surrounding atmospheric pressure. Determine this difference in pressure.

Respuesta :

solution:

the pressure difference is



P2 - P1 = (F/A)


[tex]where f is force and A=\pi \times(\frac{d^2}{4})\\

=12mm

=12\times10^{-3}[/tex]
