How is diesel fuel ignited in a diesel engine? Injected fuel is ignited by its reaction to compressed hot air in the cylinder, a more efficient process than that of the spark-ignition internal-combustion engine. The diesel engine gains its energy by burning fuel injected or sprayed into the compressed, hot air charge within the cylinder. […]
How do you calculate impedance of an inductor?
How do you calculate impedance of an inductor? The impedance of an inductor is Z = jwL. The reactance of an inductor is the imaginary part, wL. To get the reactance you multiply frequency (w) times Henrys to get Ohms of reactance. How do you find the voltage drop across an inductor? Transient Curves for […]
What does a trouble code indicate?
What does a trouble code indicate? DTC’s, or Diagnostic Trouble Codes, are used by automobile manufacturers to diagnose problems related to the vehicle. They are how the OBD-II (in light duty vehicles) or J1939 (in heavy duty vehicles) identifies and communicates to technicians where and what on-board problems exist. How do you read trouble codes? […]
What is the atomic packing factor for BCC?
What is the atomic packing factor for BCC? Body-centered cubic Because the volume of each of the eight corner atoms is shared between eight adjacent cells, each BCC cell contains the equivalent volume of two atoms (one central and one on the corner). What is the packing fraction of BCC unit cell? They occupy the […]
What is a potential hazard to your head?
What is a potential hazard to your head? Potential Hazards: Head trauma from falling objects. Bumping the head against fixed objects. Electric shock and burns from contact with exposed electric conductors. What are the hazards when welding? Health hazards associated with welding, cutting, and brazing operations include exposures to metal fumes and to ultraviolet (UV) […]
What are the processes of a Carnot cycle?
What are the processes of a Carnot cycle? Name the processes involved in Carnot cycle? It involves four process: isothermal expansion, adiabatic expansion, isothermal compression and adiabatic compression. What is the Carnot cycle in thermodynamics? : an ideal reversible closed thermodynamic cycle in which the working substance goes through the four successive operations of isothermal […]
What percent of carbon emissions come from India?
What percent of carbon emissions come from India? Greenhouse gas emissions by India are the third largest in the world and the main source is coal. India emits about 3 gigatonnes (Gt) CO2eq of greenhouse gases each year; about two and a half tons per person, which is half the world average. The country emits […]
What rocket did NASA just launch?
What rocket did NASA just launch? SpaceX Falcon 9 Did the Antares rocket launch? NG14 launched in October 2020. Gather friends, family, blankets and warm beverages to watch the launch of Northrop Grumman’s Antares rocket at 12:36 p.m. EST, Saturday, February 20, from the Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility. Did NASA launch […]
How does op amp increase slew rate?
How does op amp increase slew rate? The slew rate of an OTA or op-amp is proportional to the maximum current, usually available from the first stage of the circuit. Increase in the slew rate requires increase in the value of bias current source, which will increase the overall power dissipation of the circuit. How […]
What method of heat transfer does a campfire use?
What method of heat transfer does a campfire use? Radiation Is a campfire convection? There are three basic ways in which heat is transferred: convection, conduction and radiation. A campfire is a perfect example of the different kinds of heat transfer. If you boil water in a kettle, the heat is transferred through convection from […]
