Are designed to make it easier for employees to get health and safety information about chemicals? Answer: Occupational safety and health administration’s Hazard communication standard is the design that makes it easier for employees to get health and safety information about chemicals. Who is legally responsible for evaluating chemicals? The chemical manufacturer, importer, or employer […]
What can you do with a vacuum former?
What can you do with a vacuum former? Vacuum forming is a manufacturing process by which a sheet of plastic is heated and pressed over a form to create a part. This process is used to create many of the products in your home such as plastic containers, tubs, sink units, and electrical enclosures. How […]
What is the relative humidity at dew point temperature?
What is the relative humidity at dew point temperature? The dew point is the temperature the air needs to be cooled to (at constant pressure) in order to achieve a relative humidity (RH) of 100%. At this point the air cannot hold more water in the gas form. What is meant by dew point temperature? […]
How does a bipolar junction transistor work?
How does a bipolar junction transistor work? Bipolar Transistors are current regulating devices that control the amount of current flowing through them from the Emitter to the Collector terminals in proportion to the amount of biasing voltage applied to their base terminal, thus acting like a current-controlled switch. What is the basic principle of a […]
How can a diode be used as a temperature sensor?
How can a diode be used as a temperature sensor? Set the temperature to 25°C, “soak” the part for a few minutes, and record the voltage across the diode. Repeat at –40°C and +85°C. With three points taken, the slope can be determined. An expression for the diode voltage over temperature is derived by using […]
What is traffic volume in transportation?
What is traffic volume in transportation? Volume Study Traffic volume is defined as the number of vehicles crossing a section of road per unit time at any selected period. Traffic volume studies are conducted to collect data on the number of vehicles and/or pedestrians that pass a point on a highway facility during a specified […]
What is the difference between Otto and Diesel cycle?
What is the difference between Otto and Diesel cycle? Otto cycle is used by petrol ignition whereas diesel engine uses the diesel cycle. Another noteworthy difference is that the Otto cycle heat occurs at constant volume, whereas the diesel cycle works on constant pressure…. What is meant by Otto cycle? An Otto cycle is an […]
What is an example of direct measurement?
What is an example of direct measurement? ‘Direct measurement’ refers to measuring exactly the thing that you are looking to measure, while ‘indirect measurement’ means that you’re measuring something by measuring something else. For example of direct measurement is weight, distance, and so on. What is an example of indirect measurement? Example of Indirect Measurement […]
How do you calculate heat load of shell-and-tube heat exchanger?
Why are engineering ethics important?
Why are engineering ethics important? It Gives Them Ability To Push Back Against Bad Decisions It should form part of the culture of engineering, and be celebrated as something to be proud of. A grounding in ethics empowers engineers to bring concerns forward, and ensure that the proper level of scrutiny is applied to unsafe […]
