    Consider the following equation of Bernoullis theorem. \[P+\frac{1}{2}\rho {{v}^{2}}+\rho gh=K\](constant) The dimensions of K/P are same as that of which of the following?

    A)  Thrust          

    B)  Pressure

    C)  Angle           

    D)  Viscosity

    Correct Answer: C

    Solution :

     \[P+\frac{1}{2}\rho {{v}^{2}}+\rho gh=K\] (constant) So, according to principle of homogeneity, Dimensions of\[K=\]Dimensions of \[P\] \[\therefore \]\[\frac{K}{P}\]will be dimensionless, Thus, dimensions of\[\frac{K}{P}\]will be same as that of angle (because angle is also dimensionless quantity).
