Which metal is used for galvanizing? zinc coating What is the process of galvanizing steel? Hot dip galvanizing is the process of coating iron or steel with a layer of zinc by immersing the metal in a bath of molten zinc at a temperature of around 450 °C (842 °F). Galvanizing is probably the most […]

What are the types of valves?
What are the types of valves? Common types of valves include: Ball Valve. Predominantly equipped with quick-acting 90-degree turn handles, these valves use a ball to control flow to provide easy on-off control. Butterfly Valve. Check Valve. Gate Valve. Knife Gate Valve. Globe Valve. Needle Valve. Pinch Valve. What are the three types of valve […]
Can an engineering technologist become an engineer?
Can an engineering technologist become an engineer? Engineering technologists often assist engineers but after years of experience, they can also become engineers. Like engineers, areas where engineering technologists can work include product design (including improvement), fabrication and testing. What’s the difference between a technician and a technologist? While both technologist and technician jobs are interrelated, […]
What is the purpose of the Reynolds Transport Theorem?
What is the purpose of the Reynolds Transport Theorem? Reynolds transport theorem (RTT) expresses the relationship between the rate of change of extensive property of a system and for the control volume. The main purpose of the RTT is to provide the link between the system and control volume. What is the relationship between the […]

Can I sue a backyard mechanic? Yes. However, the way to sue […]
What does a negative reading on a voltmeter mean?
What does a negative reading on a voltmeter mean? If they are switched, there will be a negative voltage. If the poles of your voltmeter are correctly connected, there is a possibility that the battery suffered a phenomenon called “polarity reversal”. This is a rare phenomenon that can happen at the end of a discharge […]
