Answer 5

let me post my solution. I am having a hard time solving for P1

Answer 6

You can use the continuity equation here, right? \[\large A_1 v_1 = A_2 v_2\]

Answer 7

Where does that equation come from?

Answer 8

in this case would v1 = v2? I am assuming the vel are zero since they are negligible.

Answer 9

You've never seen it? It comes from conservation of mass, the fact the mass rate of flow is equal at each point.

Answer 10

maybe in another form. We use m dot = row*A*vel

Answer 11

if we assume inlet 1 and inlet 2 are equal than we can say mi dot = me dot

i = in and e = exit.
