Where does hydro electricity come from? Hydroelectric power is a renewable energy source which harnesses the power of moving water to produce electricity. The hydroelectric process starts long before you turn your light on at home or work. Large scale hydroelectricity projects typically involve dams. Which method is used to produce electricity in a hydroelectric […]
What is the focal length of a telescope?
How many amps can a Number 10 wire hold?
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 […]
What are the types of CMM?
What are the types of CMM? There are four main types of coordinate measuring machine (CMMs): bridge, cantilever, gantry and horizontal arm. The one you choose will be determined by what you wish to use it for. All CMMs have three orthogonal axes, X, Y and Z which operate in a 3D coordinate system. Which […]
Why does my quad not start?
Do safety glasses expire?
Do safety glasses expire? Most goggles and safety glasses can technically last up to 3 years, but there is a grey area between when something is usable and when safety has been compromised. How long should a pair of safety glasses last? one to three years What is the standard for safety glasses? ANSI Z87.1 […]
What is hydrodynamic and thermal boundary layer?
What is hydrodynamic and thermal boundary layer? This thin layer of changing velocity has been called the hydrodynamic boundary layer; a concept first suggested by Ludwig Prandtl in the year 1904. Heat transfer occurs due to heat conduction and energy transport by moving fluid within this thin layer. What is the difference between hydrodynamic and […]
What happens if you apply greater force to an object?
What happens if you apply greater force to an object? The greater the force that is applied to an object of a given mass, the more the object will accelerate. For example, doubling the force on the object doubles its acceleration. Does greater speed mean greater force? Then what do forces do to an object? […]
