Problem zu a constant-volume process, the temperature of a perfect gas changes from T to 1;. The change in entropy of the gas is proportional to which of the following expressions? T2-1, (T)( T in TzT, OTT Correct answer is marked, please give detailed explanation on how to arrive to the answer
The valve shown is the type used in the control of water in large conduits. Model tests are to be done, using 20oC water as the fluid in both the model and the prototype, to determine how the valve will operate under wide-open conditions. The prototype size is 2 m in diameter at the inlet and the model inlet diameter is 0.5 m. What flow rate is required for the model if the prototype flow rate is 15 m3 /s?...
Problem 7 The drawing shows a type of blood flow meter. Blood is conductive enough that it can be treated as a moving conductor. When it flows perpendicular to a magnetic field, electrodes can be used to measure the small voltage that develops across the vessel. Suppose the speed of the blood is 0.3 m/s, the diameter of the vessel is 5.6 mm and B = 0.6 T. What is the magnitude of the voltage that is measured? Provide detailed...

Please I want clear workings and formula used to arrive at the answer and detailed explanation for better understanding A recent project nominated for consideration at your company has a four-year cash flow of $20,000; $25,000; $30,000; and $50,000. The cost of the project is $75,000. a. If the required rate of return is 20%, conduct a discounted cash flow calculation to determine the NPV. b. What is the benefit-cost ratio for the project? c. What would the NPV of...
15. what type of report is used to confirm that all patients seen in the office on a given day also have charges ? 16. Which report analyzes the revenue of a practice for a special period of times ( typically a month or year) ? One of the providers in a practice asked for a report of yesterday’s transaction. how would this report we created? A patient is on sure whether she mailed a check last month to pay...

please be detailed and dont skip processes. thank you. Problem #1 A cannon is used to launch an explosive charge into the air with a speed of 40 m/s at an angle of 60° above the horizontal. The charge will detonate on the side of a snow-covered mountain 25 m above the level of the cannon in order to control snow buildup and prevent an avalanche. a. In the space below, diagram this situation and include coordinate axes. b. List...
