A bail is thrown vertically into the air with an initial kinetic energy of 2,500 joules [J]. As the ball rises, it gradually loses kinetic energy as its potential energy increases. At the top of its flight, when its vertical speed goes to zero, all of the kinetic energy has been converted into potential energy. Assume that no energy is lost to frictional drag, etc. How high does tie ball rise in units of meters [m] if it has a mass of 5 kilograms [kg]?

- Suppose you're converting a bill of materials for machining feedstock from the British gravitational (U.S. system) of units to International System (SI) units. Your goal is to have all of the material quantities in kilograms. Your bill of materials lists values for required weights of brass rod in pounds. To convert to these values to kilograms you first you divide by gravitational acceleration in feet per second squared to get a mass in slugs, then convert slugs to kilograms using standard conversion factors. Group of answer choices True Falsearrow_forwardProcess Fluid Mechanics for Chemical Engineers , please help in this Question , thanks.arrow_forward1. Energy consumption in a country from 2001 to 2011 increased from 1041.3 million to 1526.1 million BOE (barrels of oil equivalent). If the high calorific value (HHV) of the oil is 141,000 kJ/gallon what is the increase in energy consumption over 10 years in Joule units. What is the rate of energy consumption per year? 2. Based on data on the rate of energy consumption per year from question no. 1, if the growth rate energy 2.5% per year, calculate the doubling time (td) and what is the approximate rate of energy growth in 2021.arrow_forward
- Completely solve and box the final answer. Please show the units to show the unit cancellations. Write legibly 2. During a steady flow process, the pressure of the working substance drops from 1,380 kpa to 138 kpa, the speed increases from 61 m/s to 305 m/s, the internal energy of the open system decreases 58.1 KJ/kg, and the specific volume increases from 0.0625 m3/kg to 0.5 m3/kg. No heat is transferred, determine the work in KW if the mass flow at the rate of 272.15 kg/hr.arrow_forwardI am attaching the solution. Please explain the derivation in your handwritten form. Dont type pleasearrow_forwardChapter 7, Problem 63, there is an 'h' value that is solved when expressing half the width of the Rankine Oval that I am not quite understanding the process by which the value is solved for. Could you break down the process by which h=0.02423 m? It's been a while since I was last in school, so the mathematical method by which 'h' was solved is a little unclear to me.arrow_forward
- The title of our study is "Design and Fabrication of an Agricultural Spraying Attachment for an Autonomous Rover" we need help in the machine design part of our study, specifically Pump selection, battery selection, and center of gravity computation I already sent you the image of the rover Rover weight capacity 35 kilo grams (payload) Rover measurements: Wheel distance - 14.5 inches and 8.5 inches Rover platform size (width & length) 14.4 inches x 10.4 inches Height- 15.8 inches. Water tank selection More or less 25 liters *For tank selection we need to justify the size with the center of gravity, proving that is the maximum dimension or liters of the tank because the center of gravity will be higher making the rover prone to toppling Pump selection *Our sprayer design has two nozzles which splits using a tee splitter, we need to find the size of the pump to obtain the same discharge rate of a normal sprayer. A normal sprayer has a 12V pump and a pressure from 0.2 to 0.45 mpa…arrow_forwardA commonly used unit in everyday language to state weight is the pound (lb). There are actually several formal definitions of pound. One classification system defines a pound-mass (analogous to kg in SI units) and a pound-force (lbf) (analogous to a Newton); this is formally called English Engineering units but also commonly used in US Customary System units. The “pound” in the “pounds per square inch” of psi refers to pound-force. Hence, psi has units of force per area. Note that 1 lbf is defined as the gravitational force generated by 1 lb (mass) by multiplying it by the standard gravitational acceleration at the earth’s surface. Starting with just the two everyday conversion approximations every Canadian should know (1.00 kg ≈ 2.20 lb (mass) and 1.00 inch ≈ 2.54 cm), derive an approximation of 1.00 psi in Pa through unit conversions only (show each step).arrow_forwardWrite and take a picture of your answer with complete solution on a piece of paper and attach the picture.
