Explain bernoulli\'s principle? |
Answer» According to Bernoulli\'s principle,In case of steady flow(streamline fluid flow),non viscous, incopressible flowing in a tube having non-uniform cross-sectional area,sum of the pressure , K.E per unit volume and P.E per unit volume is constant.<br>I want its derivation!! Yaar<br>\tFor a streamline fluid flow, the sum of the pressure (P), the kinetic energy per unit volume (ρv2/2) and the potential energy per unit volume (ρgh) remain constant.\tMathematically:- P+ ρv2/2 + ρgh = constant\twhere P= pressure ,E./ Volume=1/2mv2/V = 1/2v2(m/V) = 1/2ρv2E./Volume = mgh/V = (m/V)gh = ρgh\t\t | |
