બર્નુલીનું સમીકરણ $P + \frac{1}{2}\rho {V^2} + \rho gh = K$ છે.તો $K/P$ નું પારિમાણીક સૂત્ર કોના જેવું હશે?

A

બળ

B

દબાણ

C

ખૂણો

D

શ્યાનતા ગુણાંક

Solution

(c) $P+\frac{1}{2} \rho \nu^{2}+\rho g h=K$ (constant)

So, according to principle of homogeneity,

Dimensions of $\mathrm{K}=$ Dimensions of $\mathrm{P}$

$\therefore \frac{K}{P}$ will be dimensionless,

Thus, dimensions of $\frac{K}{P}$ will be same as that of angle (because angle is also dimensinoless quantity),
