An aircraft deigned for supersonic flight utilises a delta wing, as shown. Using the values given in the table for the labelled dimensions. Calculate the total wing span. Give your answer to 3 decimal places. C
An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
15. Statements Which of these statements are correct? (Note: multiple answers possible) U Water vaporizes at 100 [OC], it cannot evaporate into room air Water droplets can evaporate into air because of their low partial pressure Water droplets can evaporate into air because of their high partial pressure When spraying water droplets into air, the temperature of the air decreases The cooling effect of spraying droplets in very humid air (close to saturation) is much lower than spraying droplets in dry air Pump energy for spraying water is high and evaporative cooling is therefore not efficient
Please provide equations that you are using so I can follow along and learn how to do this. In Jamestown, NY, a coal power plan consumes coal at a rate of 80 tons/hr. When coal burns, it generates approximately 30,000 kJ for every kg of coal burned. The cooling course for the plant is the nearby Chadakoin River nearby and, by code, the power plant cannot reject more than 13.19 x 109 MJ into the river annually. Determine the maximum average power output of this plant and it's maximum thermal efficiency. To check your work, enter the efficiency, as a decimal, in the box provided.
Please handwriting make the solution very simple not long.
Q. Blood flow. An artery of diameter 1.0 cm divides completely into capillaries, each of diameter 20 microns. There are a large number of capillaries, N, such that the net cross sectional area for these capillaries is equal to the cross sectional area of the artery. What is AP:/APa, the ratio of the pressure change per unit length along one of the capillaries (AP) to that of the pressure change per unit length along the artery (APa)?
