If `eta_(1) and eta_(2)` are the coefficients of viscosity of two liquids, `d_(1) and d_(2)` their densities and `t_(1) and t_(2)` the flow times in Ostwald viscometer, then:

If V_(1) and V_(2)D be the volumes of the liquids flowing out of the same tube in the same interval of time and eta_(1) and eta_(2) their coefficients of viscosity respectively then

If dimensions of critical velocity of a liquid v_c flowing through a tube are expressed as [eta^xrho^yr^z] , where eta , rho and r are the coefficient of viscosity of liquid, density of liquid and radius of the tube respectively, then the values of x , y and z are given by :

If eta represents the coefficient of viscosity and T the surface tension. Then the dimensions of T//eta are same as that of

If eta represents the coefficient of viscosity and T the surface tension. Then the dimensions of T//eta are same as that of

If eta is the coefficient of viscosity and T is the temperature in kelvin, a linear plot is obtained for

A thin horizontal movable plate P is separated from two fixed horizontal plates P_1 and P_2 by two highly viscous liquids of coefficient of viscosity eta_(1) and eta_(2) as shown, where eta_2 = 4eta_(1) . Area of contact of movable plate with each fluid is same. If the distance between two fixed plates is h, then the distance h1 of movable plate from upper fixed plate such that the movable plate can be moved with a constant velocity by applying a minimum constant horizontal force F on movable plate is (assume velocity gradient to be uniform in each liquid).
