Uncover Besavilla’s solution. Compare it to your own. Ask: Why did he skip that step? Where did that formula come from? Often, he combines multiple algebraic steps into one. This is the gold you are looking for.
Besavilla starts with dense tables of specific gravities and viscosities. His unique contribution is the "solved problems" section, which includes 50+ problems on capillary rise and viscosity torque problems (e.g., a rotating cylinder in a viscous fluid)—a classic UPD exam question. fluid mechanics and hydraulics besavilla pdf upd
This is where UPD students struggle. The theoretical derivations in standard textbooks are complex. Besavilla provides direct formulas for flow rate through an orifice (with coefficient of velocity and contraction) and gives a simple table for weir formulas (Rectangular, Cipolletti, Triangular). The PDF includes a massive set of problems involving tanks discharging through multiple orifices. Uncover Besavilla’s solution
