What type of waste is most commonly produced in hospitals? These are infectious wastes, hazardous wastes, and radioactive wastes. Of these three hospital waste sub-categories, infectious and anatomical wastes — like surgical waste or bloody bandages — make up the majority. Which waste is used in landfilling? Municipal solid waste (MSW) and faecal sludge are […]
What causes crankcase Blowby?
What causes crankcase Blowby? When you combine a large cylinder bore, high cylinder pressure through turbocharging, many hours of use and marginal maintenance, excessive blowby is the result. The leakage of any combustion gases, air, or pressure into the engine’s crankcase is considered blowby. What are crankcase emissions or blowby gases are? The unwanted gases, […]
How do we reduce carbon monoxide?
How do we reduce carbon monoxide? Steps to Reduce Exposure to Carbon Monoxide Keep gas appliances properly adjusted. Consider purchasing a vented space heater when replacing an unvented one. Use proper fuel in kerosene space heaters. Install and use an exhaust fan vented to outdoors over gas stoves. Open flues when fireplaces are in use. […]
What is vertical centrifugal pump?
What is vertical centrifugal pump? Vertical centrifugal pumps for low viscosity fluids Vertical inline centrifugal pumps, as their name implies, are single stage centrifugal pumps that are specifically designed for vertical installation. Vertical centrifugal pumps are common for the transfer of low viscosity fluids over a range of flow rates and heads. What are the […]
Why is recycling batteries good for the environment?
Why is recycling batteries good for the environment? Recycling batteries saves natural resources, because plastic and metals from used batteries can be used to make new batteries and protects the environment by keeping heavy metals out of landfills and the air. How should you dispose of batteries safely? Simply take any batteries which you need […]
How do you calculate the mechanical load of a motor?
Which method of determining volume is more accurate?
Which method of determining volume is more accurate? Using the smallest graduated cylinder possible allows for a more accurate measurement. Ask students to estimate the volume of water that will be displaced, and match the size of the graduated cylinder to the estimate. What is the method of finding volume? For less defined shapes, volume […]
What happens to the current in a circuit if a 10 Ω resistor is removed and replaced by a 20 Ω resistor?
What is the step in the design process where you identify a problem or need that exists?
What is the step in the design process where you identify a problem or need that exists? The steps: The steps: ask to identify the need and constraints, research the problem, imagine possible solutions, plan by selecting the most promising solution, create a prototype, test and evaluate the prototype, and improve and redesign as needed. […]
How piezoelectric transducer can be used for pressure measurement?
How piezoelectric transducer can be used for pressure measurement? When a force is applied to a piezoelectric material, an electric charge is generated across the faces of the crystal. This can be measured as a voltage proportional to the pressure (see diagram to the right). As a result, piezoelectric sensors are not normally suitable for […]
