How do you calculate mass flow in a pipe? A units check gives area x length/time x time = area x length = volume. The mass m contained in this volume is simply density r times the volume. To determine the mass flow rate mdot, we divide the mass by the time. The resulting definition […]
Which best describes the similarities and differences between the engineering and technology pathway?
Which best describes the similarities and differences between the engineering and technology pathway? The sentence which best describes the similarities and differences between the Engineering and Technology pathway and the Science and Math pathway is: Both pathways require workers to have observational skills while the Engineering and Technology pathway requires CAD knowledge. Which tasks are […]
Is it better to finance a car through bank or dealership?
Is it better to finance a car through bank or dealership? In some cases, however, a dealer may negotiate a higher interest rate with you than what the lender offers and take the difference as compensation for handling the financing. In general, you can usually get lower interest rates on a new car through a […]

What are the four main components of refrigeration system?
What are the four main components of refrigeration system? Mechanical refrigerators have four basic elements: an evaporator, a compressor, a condenser, and a refrigerant flow control (expansion valve). A refrigerant circulates among the four elements changing from liquid to gas and back to liquid. What part of a fridge makes it cold? evaporator What is […]
What is in windshield washer fluid to keep it from freezing?
What is in windshield washer fluid to keep it from freezing? Your windshield can get colder than the temperature outside, but only after you’ve sprayed on washer fluid. Washer fluid is a mix of methyl alcohol, also known as methanol, and water. The alcohol keeps it from freezing (and bursting) in your car’s washer fluid […]
What is the difference between wrought and cast?
What is the difference between wrought and cast? Actually, the basic distinction between the two is simple: Cast iron is iron that has been melted, poured into a mold, and allowed to cool. Wrought iron is iron that has been heated and then worked with tools. In fact, the term “wrought” derived from the past […]
How do you know which vibrational modes are IR active?
How do you know which vibrational modes are IR active? In order to determine which modes are IR active, a simple check of the irreducible representation that corresponds to x,y and z and a cross check with the reducible representation Γvib is necessary. If they contain the same irreducible representation, the mode is IR active. […]
What does a high Reynolds number indicate?
What does a high Reynolds number indicate? The higher the Reynolds number, the greater the range of scales. The largest eddies will always be the same size; the smallest eddies are determined by the Reynolds number. What is the explanation for this phenomenon? A large Reynolds number indicates that viscous forces are not important at […]

What is the term for removing refrigerant in any condition from a system and storing it in an external container without necessarily testing and processing it in any way? Recycling is to. Remove refrigerant, in any condition, from a system and store it in an external container, without necessarily testing it or processing it in […]
