Choose the correct expression for the flow rate for an obstruction flowmeter.

Multiple Choice

$V^{}=A_o{C}_0\sqrt[\phantom{2}]{\frac{2(P_1-P_3)}{(1-{}^4)}}$

$V^{}=A_0{C}_0\sqrt[\phantom{2}]{\frac{2(P_1-P_2)}{(1-{}^4)}}$

$$

$V^{}=A_0{C}_0\sqrt[\phantom{2}]{\frac{2(P_1-P_2)}{p(1-{}^2)}}$

$$

$V^{}=A_o{C}_0\sqrt[\phantom{2}]{\frac{4(P_1-P_2)}{(1-{}^{\text{u}\text{a}\text{r}\text{r}})}}$
