Question

Problem 4.23 Consider an homogeneous, inviscid fluid con- tained in the opened tank below. Assume that the velocity at the surface is much samller than that at the opening (or, equivalently, the tank is sufficiently large). Assuming that the flow is steady, compute the velocity at the opening. O Vi < V2 EP V2 = ?

Answer 1

Solution: point V<<V₂ Datum TV point Applying Bernoulli's equation at point of @ at point o 8 @ pressure (P) is atmospheric pressure. e P= Patm. given, v, Seva V, can be neglected. 29 h = o tren [i point® is at datum line] (vz = Jagh.
