Compute the line integral of v = (r cos2 ?) r â€“ (r cos ? sin ?) ? 3r ? around the path shown in Fig. 1.50 (the points are labeled by their Cartesian coordinates). Do it either in cylindrical or in spherical coordinates. Check your answer, using Stokes' theorem. Attachments: compute_the_line_integral_of_1.docx .... Read More

A spherical ball of clay, 2 in. in diameter, has an initial moisture content of 10 wt%. The diffusivity of water in the clay is 5 A? 10â€“6 cm2/s. At time t = 0, the surface of the clay is brought into contact with air such that the moisture content at the surface is maintained at 3 wt%. Estimate the time for the average moisture content in the sphere to drop to 5 wt%. All moisture contents are on a dry basis. .... Read More

Liquid oxygen is stored in a thin-walled, spherical container 0.8 m in diameter, which is enclosed within a second thin-walled, spherical container 1.2 m in diameter. The opaque, diffuse, gray container surfaces have an emissivity of 0.05 and are separated by an evacuated space. If the outer surface is at 280 K and the inner surface is at 95 K, what is the mass rate of oxygen lost due to evaporation? (The latent heat of vaporization of oxygen is 2.13 X 105 J/kg.) ....

This is the same format as the other linear project you did. But it needs to be with a new topic because the one you did for me is too close to the reference document the professor is using in my husbands class. I've put attachments and some supporting stuff below. Please let me know if you need anything else. Curve-fitting Project - Linear Model (due at the end of Week 5) Instructions For this assignment, collect data exhibiting a relatively linear .... Read More

A product engineer has developed the following equation for the cost of a system component: C = (10P)2, where C is the cost in dollars and P is the probability that the component will operate as expected. The system is composed of two identical components, both of which must operate for the system to operate. The engineer can spend $173 for the two components. To the nearest two decimal places, what is the largest component probability that can .... Read More
