How is bypass ratio calculated? The bypass ratio is usually given as the mass flow of fan by the mass flow of core i.e. ˙mf˙mc:1. In some cases, it is given as the ratio of cold air to hot air, ˙mc˙mh:1. So, a bypass ratio of 9.6:1 means that 9.6 kg of air passes through […]
What is first order lag?
What is first order lag? A first-order lag relation is often used to represent the dynamic response characteristics of simple systems. For any input signal x(t) the output signal y(t) satisfies the ordinary differential equation. where τ is the “time constant” of the response. What is the first order system? Introduction: First order systems are, […]
How did Florida form geologically?
How did Florida form geologically? The land we now call Florida began to form by a combination of volcanic activity and the deposit of marine sediments. It formed along northwest Africa about 530 million years ago. As the Appalachian Mountains eroded, sand and clay were deposited over Florida�s limestone layer. Was Florida underwater at once? […]

What is the other name of concave and convex mirror?
What is the other name of concave and convex mirror? converging mirrors What are concave mirrors also called? A concave mirror, or converging mirror, has a reflecting surface that is recessed inward (away from the incident light). These mirrors are called “converging mirrors” because they tend to collect light that falls on them, refocusing parallel […]

Can forklift carry passengers?
Can forklift carry passengers? Forklifts are for carrying loads only, and should never carry people. There is a reason there is only one seat, and that’s for the forklift operator only. No passengers! Who can train someone on a forklift? In short, anyone cannot do forklift training. The trainer should be someone who has proven […]
What factors lead to software project failure?
What factors lead to software project failure? A good starting point is by addressing some of the key reasons software projects fail. Not Enough Time. Insufficient Budget. Poor Communication. Never Reviewing Project Progress. Inadequate Testing. Testing in the Production Environment. Lack of Quality Assurance. Not Conforming to Industry Standards. How does a software fail? Failure […]
What is the difference between up milling and down milling?
What is the difference between up milling and down milling? In up milling, cutter rotates against the direction of table feed. In down milling, cutter rotates along the direction of table feed. In down milling mode, the cutting force is directed downward, and thus it tends to press the workpiece rather than lift off. What […]
