ME 3332 Spring 2011 HW #9 A &B Assigned- Monday, March 21st, 2011 Due- Monday, March 28th, 2011 Source Material: Class Notes, 6.1-6.4 “Fundamentals of Fluid Mechanics” by Munson, Young, & Okiishi (5th or 6th edition). Please Show All Work and Follow the Format given on the course website for Type B Problems Type A. Section 6.1 of “Fundamentals of Fluid Mechanics” by Munson, Young, & Okiishi (5th or 6th edition). 1. A fluid has a velocity field given as: V = 2x 2 i – (2xy - 2yz) j – (2xz + z 2 ) k . What is the volumetric dilatation rate of this fluid? 2. Consider the same velocity field as problem 1. Calculate the vorticity, z. Is the flow irrotational? Section 6.2 of “Fundamentals of Fluid Mechanics” by Munson, Young, & Okiishi (5th or 6th edition). 3. The velocity field for a certain incompressible, steady flow field is V = (x 2 +y 2 ) i –(xy+yz+z) j + (g[x,y,z]) k . Determine possible functional form for g [x,y,z]. 4. The velocity field for a 2-dimensional incompressible flow, is given as V = (3yt)i + (4xt)j . Find the stream function of this flow.
