Can you help me to what the equation would work out to?

Would you subtract the square root from the right hand side to get A2 on its own, then group like terms?

to get A2 dived the right hand side by sqrt... then by cancelling out wouldn't that leave sqrt rho*g*z??

A2= A0 sqrt (rho*g*z) A2 will be greater

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

M(dot)= A1 sqrt (2(Po-B)/rho) = A2 * sqrt (2(Po-B-rho*g*z')/rho)

M= rho*A*V = rho*A*V - rho*g*z' ?

that it will always remain constant?

From earlier you said apply continuity equation Q(dot)=AV A=Q/V but now I am unsure what to do with this?

P0 = B + rho*V^2/2 - rho*g*z' v= sqrt (2(Po-B +rho*g*z')/rho)

ii) P0 = B + rho*V^2/2 + rho*g*z' v= sqrt (2(Po-B-rho*g*z')/rho)

v= sqrt (2(Po-B)/rho) ?

v= sqrt (2(B-Po)/rho) ??

stagnation Po = B+1/2* ρ*v^2 v= sqrt (B+1/2*ρ)

P +1/2*ρ*v^2+ρgz = B ??
