Whakaoti mō A
\left\{\begin{matrix}A=\frac{P}{gh\rho }\text{, }&g\neq 0\text{ and }\rho \neq 0\text{ and }h\neq 0\\A\in \mathrm{R}\text{, }&\left(g=0\text{ or }\rho =0\text{ or }h=0\right)\text{ and }P=0\end{matrix}\right.
Whakaoti mō P
P=Agh\rho
Tohaina
Kua tāruatia ki te papatopenga
Ah\rho g=P
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
gh\rho A=P
He hanga arowhānui tō te whārite.
\frac{gh\rho A}{gh\rho }=\frac{P}{gh\rho }
Whakawehea ngā taha e rua ki te h\rho g.
A=\frac{P}{gh\rho }
Mā te whakawehe ki te h\rho g ka wetekia te whakareanga ki te h\rho g.
