What is the best method to determine a chillers normal charge? What is the best method to determine a chiller’s normal charge for leak rate calculations? Use the charge stated on the equipment nameplate. Approximately how much refrigerant vapor is left in an average 350-ton R-123 chiller at 0 psig once all the R-123 liquid […]
What is the EA for the reverse reaction?
What is the EA for the reverse reaction? The activation energy for the reverse reaction, Ea(rev), is the difference between the product energy and transition state at the peak of the diagram. Hr is the difference between the potential energy of the reactant and the potential energy of the product. What is the activation energy […]

At what angle should a projectile be thrown?
At what angle should a projectile be thrown? At what angle should a projectile with initial velocity ‘v’ be thrown, so that it achieves its maximum range? For maximum horizontal rangeHmax= (u2sin2θ)/2g = (u2)/2g, implying the angle should be equal to 45°. What angle range is half? Therefore, one angle of the half of maximum […]
What are three ways static electricity can build up?
What are three ways static electricity can build up? Static buildup consists of the following three major types. Contact Static Buildup. Frictional Static Buildup. Detachment Static Buildup. What is the difference between current and electricity? Electricity is the form of energy and produced by the flow of electrons whereas current is combination of flow of […]
Is crude oil really a fossil fuel?
Is crude oil really a fossil fuel? Fossil fuels include coal, petroleum (oil), natural gas, oil shales, bitumens, and tar sands and heavy oils. Does crude oil come from dinosaurs? Oil and natural gas do not come from fossilized dinosaurs! Thus, they are not fossil fuels. It was subsequently used more ubiquitously in the early […]
Can Balance affect driving?
Can Balance affect driving? Driving on tires out of balance may cause your fuel costs to rise. The faster you drive, the more out-of-balance tires will affect driving performance, further decreasing your fuel efficiency. What affects vehicle balance? Accelerating, braking, or steering shifts the vehicle’s weight and affects vehicle balance. Vehicle Balance refers to the […]
How does belief bias impact reasoning?
How does belief bias impact reasoning? In syllogistic reasoning, people do not fully follow the principles of logic, and the reasoning process is often biased by beliefs (Evans et al., 1983, 2001). When conclusion believability does not conflict with beliefs, people are likely to endorse this argument, and syllogistic reasoning is boosted by beliefs. Why […]
Does Mass Affect period of a pendulum?
Does Mass Affect period of a pendulum? The period of a pendulum does not depend on the mass of the ball, but only on the length of the string. Two pendula with different masses but the same length will have the same period. Two pendula with different lengths will different periods; the pendulum with the […]
