what happens when velocity of a liquidbecames greater than its critical velociy?

wht's the dimensional formula of viscosity..????

assuming that the critical velocity of a viscous liquid flowing through a capillary tube depends upon radius r of a tube,density of the tube and co-efficient of viscosity of the liquid. use the method of dimensions to obtain a relation between these quantities.

Q54. Twelve identical wires are connected in the plane as shown in the figure. The six outer wires make a regular hexagon and the remaining six join the vertices of this hexagon with common centre at C. Each wire has resistance of 20 Ω. Calculate effective resistance between A and B. ( If you connect a battery across A and B, the currents in AC and CB are the same and those in DC and CE are the same)

[ IJSO Stage -II- 2015]

Q55. When 5 V are applied across the terminals of a galvanometer, 100 mA current passes through its coil and the galvanometer shows full scale deflection. With suitable modification, it can be used to measure p.d. or currents with certain sensitivities.

A shut resistance is now connected parallel to the galvanometer so that 80% of the current approaching the coil goes through the shut. This ammeter is used to measure current supplied by an ideal cell of emf 6 V, connected across a bulb of resistance 40 Ω.

Calculate the error (percentage) in the measurement of current passing through the bulb?
