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 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 […]
What should the government do to reduce road accidents?
What should the government do to reduce road accidents? The Government has approved a National Road Safety Policy. This Policy outlines various policy measures such as promoting awareness, establishing road safety information data base, encouraging safer road infrastructure including the application of intelligent transport, enforcement of safety laws. What are the effectiveness and ineffectiveness of […]
What happens to wastewater after treatment?
What happens to wastewater after treatment? What happens to the treated water when it leaves the wastewater treatment plant? The treated wastewater is released into local waterways where it’s used again for any number of purposes, such as supplying drinking water, irrigating crops, and sustaining aquatic life. What are the steps in wastewater treatment? Treatment […]
What is the process of hydraulic fracturing fracking )?
What is the process of hydraulic fracturing fracking )? Hydraulic fracturing, informally referred to as “fracking,” is an oil and gas well development process that typically involves injecting water, sand, and chemicals under high pressure into a bedrock formation via the well. What are 5 steps in the process of fracking? Check out the seven […]
How do you determine breaking strength?
How do you determine breaking strength? Method of finding the Breaking Strength (B.S) is to divide the square of the diameter of the rope in millimetres by 200. Method of finding the Safe Working Load (S.W.L) is to divide the Breaking Strength by factor of safety. What is the difference between breaking strength and tensile […]
Do volts or amps hurt you?
What factors determine the voltage rating of a capacitor?
What factors determine the voltage rating of a capacitor? Three factors determine the capacitance of a capacitor: The area of the plates. The distance between the plates. The type of dielectric used. What is breakdown voltage of capacitor? Breakdown voltage of a Capacitor Above that electric field strength , the material conducts electric charges and […]
What is the minimum sampling rate?
What is the minimum sampling rate? The minimum sampling rate is often called the Nyquist rate. For example, the minimum sampling rate for a telephone speech signal (assumed low-pass filtered at 4 kHz) should be 8 KHz (or 8000 samples per second), while the minimum sampling rate for an audio CD signal with frequencies up […]
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 […]
