Andrade’s equation has been proposed as a model of the effect of temperature on viscosity: μ = DeB∕Ta where μ = dynamic viscosity of water (10–3 N·s/m2), Ta = absolute temperature (K), and D and B are parameters. Fit this model to the following data for water: T 0 5 10 20 30 40 μ 1.787 1.519 1.307 1.002 0.7975 0.6529

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

Ifa component is made of two or more materials with different modulus of elasticity (e), it is called a composite member and we calculate the factor·n". mention the formula for calculating n". also, ifn> 1, explain what will happen to the 1. transformed.gi) ifn 1, what will happen to the material when transformed material when
