What is the Carnot efficiency of heat engine operating between 400 C and 100 C? Thus, the Carnot efficiency of heat engine is 55.42% . How do you calculate temperature efficiency? Practice Convert the high and low temperatures from Celsius to Kelvin: Thot=540oC+273=813K. Tcold=20oC+273=293K. Determine the efficiency using the Carnot efficiency formula: η=[1−TcoldThot]×100%η=[1−293K813K]×100%=64% How do […]
What are thermoplastics and thermosetting polymers?
What are thermoplastics and thermosetting polymers? Most linear polymers and branched structure polymers with flexible chains are thermoplastics. This is in contrast to thermosetting polymers, which do not soften when heated due to strong covalent crosslinks. Thermoset polymers are generally harder and stronger than thermoplastics and have better dimensional stability. What is the structure of […]
How do you test load cells?
How do you test load cells? A load cell test is performed using a digital multimeter. The digital multimeter is connected between the positive signal wire and the negative signal wire of the load cell. The output between them should be equal or to a value specified in the datasheet. This is the test for […]
What type of reaction is CO2?
What type of reaction is CO2? Combustion reactions involve the reaction of a substance with oxygen gas (O2). It is often referred to as burning. The products of the reaction are oxides of the elements in the reactants. Hydrocarbon combustion leads to the formation of carbon dioxide gas and water vapor. Is C O2 CO2 […]
How do you make clay bricks stronger?
What fluids are called Newtonian?
What fluids are called Newtonian? Water, air, alcohol, glycerol, and thin motor oil are all examples of Newtonian fluids over the range of shear stresses and shear rates encountered in everyday life. Single-phase fluids made up of small molecules are generally (although not exclusively) Newtonian. Are all fluids non-Newtonian? In reality most fluids are non-Newtonian, […]

Deductive. How do you identify premises and conclusions in arguments? If it’s being offered as a reason to believe another claim, then it’s functioning as […]
How do you make powder metallurgy?
How do you make powder metallurgy? Solid-State Reduction. The metal ore is crushed and then mixed with another material, usually carbon. Atomization. This process begins with scrap metal that is then melted. Electrolysis. The electrolysis process requires specific conditions to be effective, including proper: Chemical. Centrifugal Atomization. Are types of powder metallurgy process? Overview. History […]
Which research misconduct most likely occurred?
Which research misconduct most likely occurred? Which type of research misconduct most likely occurred if someone intentionally removes data points from the data set in order to generate a deceptive conclusion? This situation most likely involves falsification. Falsification includes deceptively changing or omitting data. What is the most appropriate process for research collaborators to use? […]
