Journal Club Torricelli didn't know about wetting
Anupam Pandey


Almost 400 years ago Torricelli predicted the efflux velocity of a liquid jet coming out of an orifice below a tank. This purely inviscid description is found to overestimate experimental results as it doesn’t incorporate any dissipation. The paper I will present today (Phys. Rev. Lett. 117, 248002) shows a dramatic dependence of the exit velocity on the wetting properties of the outer surface of the tank bottom plate. In this journal club, I will discuss critically the experimental results and theoretical arguments presented in this paper.
