"What pressure do you need to get water to flow at 2 m/sec coming out of a hole?"

Here is the visual of a container sitting on top of a glass of water with a hole poked through the bottom: http://i96.photobucket.com/albums/l168/synovial/fluids.jpg

Given: A

Find: p

Useful equations:

Bernoulli's Equation:

p

A

I'm not sure how to modify the Bernoulli's equation to combine the y

Here is the visual of a container sitting on top of a glass of water with a hole poked through the bottom: http://i96.photobucket.com/albums/l168/synovial/fluids.jpg

Given: A

_{1}, A_{2},*V*_{2}, (y_{1}-y_{2})Find: p

_{atm}Useful equations:

Bernoulli's Equation:

p

_{1}+[tex]\rho[/tex] [tex]\cdot[/tex] g [tex]\cdot[/tex] y_{1}+ 0.5 [tex]\rho[/tex][tex]\cdot[/tex]*V*_{1}^{2}= p_{1}+[tex]\rho[/tex] [tex]\cdot[/tex] g [tex]\cdot[/tex] y_{2}+ 0.5 [tex]\rho[/tex][tex]\cdot[/tex]*V*_{2}^{2}A

_{1}*V*_{1}= A_{2}*V*_{2}I'm not sure how to modify the Bernoulli's equation to combine the y

_{1}and y_{2}into (y_{1}- y_{2}) and to also combine the pressures into p_{atm}. Can someone please help me?
