MAE 2315: Fluid Dynamics
October 6, 2016
Answer the questions in the spaces provided on the question sheets. If you run out
of room for an answer, continue on the back of the page.
The Richardson number, Ri, which correlates the production of turbulence by buoyancy,
is a dimensionless combination of the acceleration of gravity g, the fluid temperature To, the local
temperature gradient T/z, and the local velocity gradient u/z.
Water at 20C, in the pressurized
tank of Fig. P3.117, flows out and creates a
vertical jet as shown. Assuming steady
frictionless flow, determine the height H
to which the jet rises.
1.6 The Saybolt Universal Viscometer, now obsolete but still sold in scientific catalogs,
measures the kinematic viscosity of lubricants [Ref. 49, p. 40]. A container, held at constant
temperature, is filled with 60 ml of fluid. Measure the time t for the
P3.13 The cylindrical container in Fig. P3.13
is 20 cm in diameter and has a conical contraction
at the bottom with an exit hole 3 cm in diameter.
The tank contains fresh water at standard sea-level
conditions. If the water surface is falling at the

gage A reads 83 kPa and gage B reads 105 kPa. Express these readings in gage or vacuum
pressure, whichever is appropriate.
Solution: We can find atmospheric pressu
For the incompressible plane flow of Prob. P4.6, with velocity components u =

2.109 The float level h of a hydrometer is a measure of the specific gravity of the liquid. For
stem diameter D and total weight W, if h 0 represents SG 1.0, derive a formula for h as a
function of W, D, SG, and o for water.
Solution: Let submerged volume
