Dry air enters an inclined pipeline in the upward direction being preheated. The pipe has an inner diameter of 0.3 m and a total length of 5 m with a 30° inclination from the horizontal direction. The air enters at 300 kPa (absolute) with a velocity at 3 m/s, density of 3 kg/m³, and at an ambient temperature of 20°C. The electrical heaters around the pipe surface provides a uniform heating flux of 2 kW/m² and the exiting pressure was measured to be 150 kPa. Assume ideal gas behavior, and the air specific heat can be approximated as Cp = 900+ 0.37 (where T is in Kelvin). Please calculate the exiting temperature of the air. You may need the following formula: The formula for the roots of a general quadratic equation ax² + bx+c = 0 is -b ± √b²-4ac 2a

What is my GPA if I have 5 A's and 1 D

Problem- Cargo ships can cause a lot of air pollution.Solution-  to use nuclear powered ships since they hold a lot of energy and can travel for long distances. How it will work is that it will need a nuclear reactor at the bottom of the boat to heat up the water and then turn it to electricity to power the boat. The boat will be made out of graphene which is a tough material to avoid any leaks in the boat. It will also contain many control rods because nuclear power is so powerful that it can create to much energy to handle. With control rods, you can slow down this process and keep it in a controlled manner. Since cargo ships are already is the ocean, there will be no need for any extra materials to make it work. -Do you think this will work? Why/Why not?  -What do you think is wrong with it/ How can this be improved? Please send this to someone else I need to record 50 responses for a science project. Thank you!

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?

Task 1 You have been moved into the laboratory for the fluid testing for hydraulic devices and a considerable amount of research has been carried out in an attempt to understand the exact nature of the temperature variation of viscosity. Inspect the table given below and note the relative values of viscosity for each Newtonian fluid at a given temperature. Compare the results of a viscosity test and comment on why the viscosity of ethanol and water is considerably lower than motor oil and explain any discrepancies. Temperature [°C] Water (μ) Ethanol (μ) Motor oil (SAE 15W-40) (μ) [mPa s]/ cP [mPa s]/ cP [mPa s]/ cP 10 1.30600 1.4475 582.95 20 1.00160 1.1841 287.23 30 0.79722 0.9764 155.31 40 0.65272 0.8151 91.057 50 0.54650 0.694 57.172 60 0.46602 0.6034 38.071 70 0.40353 0.5231 26.576 80 0.35404 0.01043 19.358 90 0.31417 0.01074 14.588 100 0.28158 0.1104 11.316 To complete this task, it is required to evaluate the effects of shear force on three Newtonian and three non-Newtonian…
