Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Since there is no instructions given about the fluid... taking general case of water. So density (d) = 1g/cm³ dynamic viscosity (u) = 0.01g/cm•sec Also for turbulent flow, Reynolds number(Re)= 2000(in general). Also velocity of the flow (v) = 1cm/s So depth (D) = ? Re = (d×v×D)/u (u×Re) /(d×v) = D D= 0.01×2000/1×1= 20cm . So correct option should be (B)...
