What is plant machinery and equipment? The term ‘plant’ refers to machinery, equipment and apparatus used for an industrial activity. Very broadly, ‘tools’ might be considered to be instruments that are used by hand, whereas ‘equipment’ might refer to a set of tools used for a single purpose. What precautions should you take around machinery? […]
How do you calculate specific gravity from specific weight?
How do you calculate specific gravity from specific weight? Multiply the density by the acceleration of gravity (9.81) to calculate the specific weight. In our example, the specific weight is 840 x 9.81 = 8,240.4. Measure or obtain elsewhere the volume of the substance. Convert the volume to the cubic meter unit. What is the […]
Why is entropy J K?
How can you tell if your boyfriend is mad at you?
What are the different types of heat exchangers?
What are the different types of heat exchangers? Types of Heat Exchangers Shell and tube heat exchangers. Double pipe heat exchangers. Plate heat exchangers. Condensers, evaporators, and boilers. What is the best type of heat exchanger? The parallel-flow heat exchanger is the most suitable one if the area is an important parameter where as the […]
What are the strengthening mechanisms in superalloys?
What are the strengthening mechanisms in superalloys? Possible operative mechanisms include solid-solution strengthening of the γ matrix and γ′ precipitates, grain size hardening of both the γ matrix and the primary γ′ precipitates, and shearing of each population of precipitates. Which of the following is a strengthening mechanism? Explanation: Grain size reduction, solid solution strengthening […]
What are the advantages of helical gears over spur gears?
What are the advantages of helical gears over spur gears? Another advantage of helical gears over spur gears is in torque capacity. Spur gears, by design, are weaker than helical gears because loads are transmitted over fewer teeth. Helical gearing is machined with angled teeth, then hardened and ground, which is complex but necessary to […]
What is IR spectroscopy used for?
What is IR spectroscopy used for? Infrared (IR) spectroscopy is a vibrational spectroscopic technique based on the absorption of infrared radiation by matters that excite vibrations of molecular bonds. It is a powerful method for investigating structural, functional, and compositional changes in biomolecules, cells, and tissues. What is the principle of IR spectroscopy? The IR […]
How do you increase the depth of field on a microscope?
How do you increase the depth of field on a microscope? Place your aperture in front of the microscope lens centering the aperture. For some gross-specimen low-magnification ‘scopes, this is relatively easy since the lens is quite large. The field-stop acts as an outboard aperture to limit the light entering the lens to the centre. […]
What is the difference between Cancelled revoked and suspended?
What is the difference between Cancelled revoked and suspended? A suspended driver’s license means your license is temporarily out of service. A revoked driver’s license means your license has been fully canceled and cannot be reinstated. It is possible to have your driver’s license revoked or even permanently revoked due to multiple driving offenses, medical […]
