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 […]
What is the maximum shear stress in a thin walled pressurized sphere?
What is the maximum shear stress in a thin walled pressurized sphere? A pressure vessel is assumed to be a thin walled pressure vessel when the thickness of the vessel is less than 1/20 of its radius….List of Equations: Parameter Formula Maximum out-plane shear stress (τmax(out plane)) (pgr)/(2t) Spherical pressure vessel Hoop stress (σ1) (pgr)/(2t) […]
How do you harden teeth with gears?
How do you harden teeth with gears? Induction hardening or selective heating may be employed to harden just the gear teeth only, which can be an effective method of reducing the distortion in a gear. Masking of journals and keyways may be employed in case hardening processes to keep them soft and allow for easier […]
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 […]
How does gravity affect a car?
How does gravity affect a car? Gravity has a major effect on your vehicle when you are driving downhill or uphill. When you are driving uphill, gravity’s power is working against you, meaning it pulls your car the opposite direction, which slows down your car. You will need more engine power in order to stay […]
