Question

Critical velocity depends on the mass true hai ki false

Answer 1

Explanation:

it is true

critical velocity depends on mass

Answer 2

True,Critical velocity depends on the mass.

Explanation:

• At critical velocity the liquid flow turns from streamlined to turbulent

• The critical velocity is the direction and the speed at which the liquid flows

• Basic formula for calculating critical velocity: Vcrit = (Nr_µ) / (D_ρ)

• This depends on coefficient of viscosity, inner diameter of the pipe,  density of the given liquid

• The coefficient of viscosity  is measured in meters-squared per second

• The density of the given liquid is measured in kilograms per meter-squared.

• The Reynolds number is a dimensionless variable and  lies between 0 and 2320
