ADVANCED CHEMISTRY! RATE WILL BE GIVEN! PLEASE WRITE THE COMPLETE SOLUTIONS A Steam at 400 deg C an 8,200 kilo Pascals enters a turbine and leaves at 10 kPa. What is the entropy of the leaving steam if the efficiency of the turbine is 0.76. Round the answers in to 2 decimal places. Hint: Turbine's efficiency is the ratio of work delivered by the actual turbine to the work delivered by an isentropic turbine (no entropy change)   H (kJ/kg) S (kj/kg-K) 8200 kPa, 400 degrees 3137.6 6.3534 10 kPa, sat. liquid 191.832 0.6493 10 kPa, sat. vapor 2584.8 8.1511

Case Study: Paula’s Pain Paula has worked for Brindle Corporation for 3 years.  During this time, she has worked as a machine operator/cell leader in various work cells.  Recently, the plant went to mandatory 12-hour shifts and plans to remain on this schedule for several months. Paula’s present work cell is manufacturing 3-inch diameter exhaust tubes that are made from stainless steel.  These tubes get a hole punched in them, a flange welded on, and burrs ground off.  The pipe then gets placed into a gage to check that it was made correctly.  (The tubes weigh about six pounds.) Paula has been performing the welding operation.  She leans into the machine and loads the part into a fixture then positions the flange.  Both pieces are clamped (using hand clamps) into position and the machine is cycled by depressing two palm buttons. The gaging operation requires placing the finished part into the gage and clamping it (using hand clamps) into place. A pin is depressed to verify the position…

Question 20 of 20 < A Water Balloon Battle. You are launching water balloons at a rival team using a large slingshot. The other team is set up on the opposite side of a flat-topped building that is 30.0 ft tall and 50.0 ft wide. Your reconnaissance team has reported that the opposition is set up 10.0 m from the wall of the building. Your balloon launcher is calibrated for launch speeds that can reach as high as 100 mph at angles between 0 and 85.0° from the horizontal. Since a direct shot is not possible (the opposing team is on the opposite side of the building), you plan to splash the other team by making a balloon explode on the ground near them. If your launcher is located 55.0 m from the building (opposite side as the opposing team), what should your launch velocity be ((a) magnitude and (b) direction) to land a balloon 5.0 meters beyond the opposing team with maximum impact (i.e. maximum vertical speed)? (a) Number i (b) Number i Units Units UNITS CHOICES: no units, degrees, s,…

Question * In an engineering department, the acceptance in the civil major and the acceptance in the mechanical major are two independent events. However, it is more likely to be accepted in the mechanical major. The probability to be accepted in both majors is 0.012, however to be accepted in at least one major is 0.208. Let “C" be the event the acceptance in the civil major and let "M" be the event the acceptance in the mechanical major. Then: O P(C)=0.02 and P(M)=0.6 P(C)=0.1 and P(M)=0.12 P(C)=0.06 and P(M)=0.2 O None of these

Question 11) Roger gave the following account of a roller-coaster ride: 1 tried a brand-new ride at a science centre. There's a computer screen that tells you how much the car and the people in it weigh and how high and fast you travel. You get into the car and they strap you in. The car weighs 600 kg. At the top, it moves horizontally at a speed of 1 m/s. Then you drop 30 m, make a loop into the air and finish by riding over an 8-m hill. I don't remember our maximum speed or our speed at the top of the loop, but the ride was fantastic!" Answer the following questions without taking the force of friction into consideration. Show your calculations for each question. A v=1 m/s 20 m 8 m a) What is the highest speed Roger could have attained? What is the potential energy of the roller-coaster car when it is at the top of the b) loop? c) What is the kinetic energy of the car as it passes over the top of the 8 m hill? d) What is the total mechanical energy of the system?

15) "Questions 13 and 14. If the fan moves 85 m3 of air per hour through the basement, this is the equivalent of a 50.03 cfm (cfm=cubic feet per minute) bathroom fan. Assuming the density of the air is 1.1123 kg/m3 and that 50% of the ventilated air makes contact with the walls for long enough to reach the wall temperature, using the psychrometric chart, how much moisture will be moved into or out of the basement in 24 hours (using conditions from questions 9, 10, 11, and 12) ? 14) What is the total weight (in kg) of the water vapour that is removed or added to the basement in 24 hours? (within 5%)" "16. You have just moved to a hot, dry climate where it is 37C and 20% rh, and the heat is starting to get to you. Luckily you remember from your Building Science education mention of something called a swamp cooler (evaporative cooler, that cools air by EVAPORATING water into the air). Before building one, you want to know to what temperature you could cool the air to without exceeding 80%…
