- SUPPOSE THE AMBIENT TEMPERATURE IS 20degrees CELSIUS, AND THE HOT RESERVOIR CONSISTS OF A SPHERICAL TANK WITH A RADIUS OF 4.00 m, THAT ACTS AS AN IDEAL EMITTER OF RADIATION. IF ALL THE RADIANT ENERGY EMITTED BY THE TANK COULD BE CAPTURED, WHAT IS THE AVERAGE AMOUNT OF WORK THAT COULD BE DONE EACH SECOND? ( please only answer if your 100% correct) (show work)A solid right circular cone has SG = 0.99 and fl oatsvertically as in Fig. Is this a stable position forthe cone?In the early 1900s, the British chemist Sir CyrilHinshelwood quipped that fl uid dynamics study was dividedinto “workers who observed things they could notexplain and workers who explained things they could notobserve.” To what historic situation was he referring?
- Answer 3-19Please include solution and brief reflection.I need full steps on how we derive this equation please. I need it step by step and in the simplest way possible :)Hello, Please listen to me carefully. I need "What is the temperature of the Sun (google for the answer)? What is there-entry temperature of the Space Shuttle (google for the answer)? Whydon’t you burn up at the reentry temperature that you’ve calculated for thisMach 20 flow? The answer to this question will lead you to recognize thatFigure 4.6 is wrong and that the body should actually re-enter the Earth’satmosphere in the opposite direction. (ie.. blunt/flat surface first.)" to be answered based on the main question ******Dont solve for the main question as I dont want it. ******
- 9-94: Repeat Prob. 9–93, but let the inner cylinder be stationary and the outer cylinder rotate at angular velocity ?o. Generate an exact solution for u?(r) using the step-by-step procedure discussed in this chapter. I have done 9-93 and know it is on here already but here is the problem statement for it: 9-93: An incompressible Newtonian liquid is confined between two concentric circularcylinders of infinite length— a solid inner cylinder of radius Ri and a hollow, stationaryouter cylinder of radius Ro (Fig. P9–93; the z-axis is out ofthe page). The inner cylinder rotates at angular velocity ?i .The flow is steady, laminar, and two-dimensional in ther? -plane. The flow is also rotationally symmetric, meaningthat nothing is a function of coordinate ? (u? and P arefunctions of radius r only). The flow is also circular,meaning that velocity component ur = 0 everywhere.Generate an exact expression for velocity component u? asa function of radius r and the other parameters in theproblem.…Hello, can you please help me with this question attatched, I dont undersand how they got those answers.Consider a thin-walled, fi xed-volume container of volume V that holds an ideal gas at constant temperature T. It can be shown by dimensional analysis that the number of particles striking the walls of the container per unit area per unit time is given by nv-/4, where as usual n is the particle number density. The container has a small hole of area A in its surface through which the gas can leak slowly. Assume that A is much less than the surface area of the container. (a) Assuming that the pressure inside the container is much greater than the outside pressure (so that no gas will leak from the outside back in), estimate the time it will take for the pressure inside to drop to half the initial value. Your answer should contain A, V, and the mean molecular speed v-. (b) Obtain a numerical result for a spherical container with a diameter of 40 cm containing air at 293 K, if there is a circular hole of diameter 1.0 mm in the surface.
