5. A candy company distributes boxes of chocolates with a mixture of creams, toffees, and cordials.Suppose that the weight of each box is 1 kilogram, but the individual weights of the creams, toffees,and cordials vary from box to box. For a randomly selected box, let X and Y represent the weights ofthe creams and the toffees, respectively, and suppose that the joint density function of these variablesis- (24xy, 0s x< 1, 0

As we explained in Chapter 10, viscosity is a measure of how easily a fluid flows. For example, honey has a higher value of viscosity than does water because if you were to pour water and honey side by side on an inclined surface, the water will flow faster. The viscosity of a fluid plays a significant role in the analysis of many fluid dynamics problems. The viscosity ofwater can be determined from the following correlation:μ = c1 10c2 1(T−c3 )whereμ = viscosity (N/s.m2 )T = temperature (K)c1=2.414×10-5 (N/s.m2 ) c2= 247.8 K c3= 140 KUsing Excel, create a table that shows the viscosity of water as a function oftemperature in the range of 0° C (273 15 ) to 100° C (373 15 ) in increments of 5° C. Also create a graph showing the value of viscosity as a function of temperature.
The air resistance to the motion of a vehicle is something important that engineers investigate. As you may also know, the drag force acting on a car is determined experimentally by placing the car in a wind tunnel. For a given car, the experimental data is generally represented by a single coefficient that is called the drag coefficient. It is given by the relationship: Fa C, = where C, = drag coefficient F, = measured drag force (Ib) p = air density (slugs/ft') V = air speed inside the wind tunnel (ft/s) A = frontal area of the car (ft²) What is the appropriate unit for C, if the preceding equation is to be homogeneous in units?
