1. ### Bernoulli's Equation- on a jet nozzle

Can you help me to what the equation would work out to?
2. ### Bernoulli's Equation- on a jet nozzle

Would you subtract the square root from the right hand side to get A2 on its own, then group like terms?
3. ### Bernoulli's Equation- on a jet nozzle

to get A2 dived the right hand side by sqrt...... then by cancelling out wouldn't that leave sqrt rho*g*z??
4. ### Bernoulli's Equation- on a jet nozzle

A2= A0 sqrt (rho*g*z) A2 will be greater
5. ### Bernoulli's Equation- on a jet nozzle

M(dot) is the mass flow rate M(dot)= A0 sqrt (2(Po-B)/rho) = A2 * sqrt (2(Po-B+rho*g*z')/rho) where A0 is exit area at nozzle A2 is a vertical distance z below nozzle i have also subbed in v from part i and part ii
6. ### Bernoulli's Equation- on a jet nozzle

M(dot)= A1 sqrt (2(Po-B)/rho) = A2 * sqrt (2(Po-B-rho*g*z')/rho)
7. ### Bernoulli's Equation- on a jet nozzle

M= rho*A*V = rho*A*V - rho*g*z' ?
8. ### Bernoulli's Equation- on a jet nozzle

that it will always remain constant?
9. ### Bernoulli's Equation- on a jet nozzle

From earlier you said apply continuity equation Q(dot)=AV A=Q/V but now I am unsure what to do with this?
10. ### Bernoulli's Equation- on a jet nozzle

P0 = B + rho*V^2/2 - rho*g*z' v= sqrt (2(Po-B +rho*g*z')/rho)
11. ### Bernoulli's Equation- on a jet nozzle

ii) P0 = B + rho*V^2/2 + rho*g*z' v= sqrt (2(Po-B-rho*g*z')/rho)
12. ### Bernoulli's Equation- on a jet nozzle

v= sqrt (2(Po-B)/rho) ?
13. ### Bernoulli's Equation- on a jet nozzle

v= sqrt (2(B-Po)/rho) ??
14. ### Bernoulli's Equation- on a jet nozzle

stagnation Po = B+1/2* ρ*v^2 v= sqrt (B+1/2*ρ)
15. ### Bernoulli's Equation- on a jet nozzle

P +1/2*ρ*v^2+ρgz = B ??
