What is the isentropic efficiency of a turbine? Hence, the definition of isentropic efficiency of turbine is the ratio of the actual work output of the turbine to the work output of the turbine if the turbine undergoes an isentropic process between the same inlet and exit pressures. Compressors and pumps, when undergo a steady-flow […]
How triangular wave is generated?
How triangular wave is generated? ➢ Triangular waveform can also be generated by integrating square wave from an astable multivibrator. ➢ The cycle from the square wave to the next operational amplifier repeats and generates a triangular waveform. ➢ Triangular waveform can also be generated by integrating square wave from an astable multivibrator. What is […]
What happens when you spin a bearing?
What happens when you spin a bearing? A spun bearing is bad news because it usually seizes itself around the crankshaft journal. Spun rod bearings are the most common failure. A spun rod bearing will tear up the big end bore in the rod, ruin the rod journal on the crankshaft, and sometimes break the […]
What are the main sources of error in this experiment?
What are the main sources of error in this experiment? Common sources of error include instrumental, environmental, procedural, and human. All of these errors can be either random or systematic depending on how they affect the results. Instrumental error happens when the instruments being used are inaccurate, such as a balance that does not work […]
When can you turn left when the traffic light is red?
When can you turn left when the traffic light is red? Signal and stop for a red traffic light at the marked limit line. If there is no limit line, stop before entering the crosswalk. If there is no crosswalk, stop before entering the intersection. You may turn left into a left-moving, one-way street if […]
Is it best to grip the steering wheel at 10 and 2?
What happens when heat is transferred by convection?
What happens when heat is transferred by convection? Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated. The […]
When you are stopped by a law enforcement officer you should?
When you are stopped by a law enforcement officer you should? If You Are Stopped By A Police Officer Keep your hands in plain view at all times, preferably on the steering wheel and refrain from making any sudden movements. Wait for the officer to request your license, registration, and evidence of insurance. When driving […]
Which of the following is not a metric system?
Which of the following is not a metric system? Millimeters, centimeters and meters are the metric units of length and inches is the non-metric unit of length. What are the 4 most common metric units of length? In the metric system of measurement, the most common units of distance are millimeters, centimeters, meters, and kilometers. […]
What are the 3 mechanisms of heat transfer?
What are the 3 mechanisms of heat transfer? The Three Mechanisms of Heat Transfer: Conduction, Convection, and Radiation. Which mechanism of heat transfer is dramatically increased when the surface area of an object increases? Because the number of collisions increases with increasing area, heat conduction is proportional to the cross-sectional area—a second factor in the […]
