    A partially submerged body is towed in water. The resistance R to its motion depends on the density p, the viscosity u of water, length L of the body, velocity v of the body and acceleration due to gravity g. using Buckinghan's heorem of dimensional analysis, express R in terms of dinensionless parameters

    • @Corvanor
      @Corvanor 5 років тому +23

      It doesn't matter which one you take from the geometric, flow or fluid property, as long as you don't take two of the same and don't select a dependant variable. For example, in the same pi group you can't have diameter and length because both have the same unit.

    Great explanation. However I would have liked if you explained why you prefer a variable over another while selecting pi terms. Also, what kind of term is Q? Is it flow property?

    • @MD-en6ji
      @MD-en6ji 5 років тому

      I think the variables are chosen to make common dimensionless numbers like Reynold's Number or Weber Number. I'm also guessing Q, the "Discharge" is volumetric flowrate in (m^3)/s

    • @MegaKhairul96
