The cirtical velocity (upsilon) of flow of a liquied through a pipe of radius (r ) is given by upsilon = (eta)/(rho r) where rho is density of liquid and eta is coefficient of visocity of the liquied. Check if the relaiton is correct dimensinally.

The rate flow (V) of a liquid through a pipe of radius (r ) under a pressure gradient (P//I) is given by V = (pi)/(8)(P R^4)/(I eta), Where eta is coefficient of visocity of the liquied. Check whether the formula is correct or not.

Molar enthalpy of vaporization of a liquid is 2.6 kJ. If boiling point of this liquid is 160^(@)c , the molar entropy of vaporization (in JK^(-1) ) unit is

The units of surface tension and viscosity of liquids are respectively "______________" .

Assertion: The velocity of flow of a liquid is smaller when pressure is larger and viceversa. Reason: According to Bernoulli's theorem, for the stream line flow of an ideal liquid, the totla energy per unit mass remains constant.

Statement I: The smaller unit for measuring volume of liquids is millilitre. Statement II: In standard international system volume is measured in cubic metre

A capillary tube of length 25 cm and diameter 0.1cm is fitted horizontally to a vessel full of a liquid of coefficient of visocity 0.012 cgs unit. The depth of the capillary tube below the surface of liquid is 15 cm. If the density of liquid is 0.8 g//cm^(3) , calculate the amount of the liquid that will flow out in 7 minutes. Take g=980 cm//s^(2)
