using the illustration when both surfaces 1 and 2 are exposed to the atmoshere, `P_1` and `P_2` are gauge pressure , and `h_1` and `h_2` are heights .

The Bernoulli equation for this situation is `h_1+P_1 /W+V_1^2/"2a"=h_2+P_2/W+V_2^2/"2a"`
The value of `P_1` and `P_2` are such that

A

`P_1 = P_2 = 0 `

B

`P_2lt P_1 `

C

`P_1 gt P_2`

D

`P_1// P_2 = 0`

Text Solution

Verified by Experts

The correct Answer is:
A
Since pressure is measured in gauge , pressure and `P_1` and `P_2` are measured at surfaces exposed to the atmosphere `P_1=P_2 =0`
