How do you find the heat capacity of a calorimeter? Part I: Heat Capacity of the Calorimeter The heat capacity, C, of a substance is the amount of heat required to raise the temperature of a given quantity of the substance by 1 degree. The relationship between heat capacity and specific heat is C = […]
What is the relation between compression ratio and the efficiency of the Otto cycle?
What is the relation between compression ratio and the efficiency of the Otto cycle? Explanation: This is the expression for efficiency of Otto cycle and rk=compression ratio=Vmax/Vmin. Why is Otto cycle more efficient? 3. 6 Diesel Cycle. Although for a given compression ratio the Otto cycle has higher efficiency, because the Diesel engine can be […]
Is it bad if you drive with your emergency brake on?
What is continuous system?
What is continuous system? A continuous system is one in which important activities of the system completes smoothly without any delay, i.e. no queue of events, no sorting of time simulation, etc. When a continuous system is modeled mathematically, its variables representing the attributes are controlled by continuous functions. Is age a discrete or continuous? […]
What are construction closeout documents?
What are construction closeout documents? Project closeout is the final construction phase of the project lifecycle. It is the collecting of final project documents (sometimes referred to as project deliverables), assembling them into a package, and ultimately presenting that package to the client that requested the project be built. How do you close a construction […]

How do you calculate the voltage across a capacitor?
What happens to GDP when prices increase?
What happens to GDP when prices increase? Over time, the growth in GDP causes inflation. This is because, in a world where inflation is increasing, people will spend more money because they know that it will be less valuable in the future. This causes further increases in GDP in the short term, bringing about further […]
What is needed for 3D printing?
What is needed for 3D printing? The two materials required for 3D printing are Poly Lactic Acid (PLA) and Acrylonitrile Butadiene Styrene (ABS). Both are thermoplastics that will become soft and malleable when heated, frozen when cooled. How does a 3D printer work step by step? The 3D printing process turns a whole object into […]
