What does the U-tube manometer measure? A mercury filled U-tube manometer is used to measure the flowrate of air in a pipe. One leg of the manometer is connected to the upstream side of an orifice plate and the other leg is connected to the downstream side. We can only determine the differential pressure but […]
What can minimize engine effort and save fuel?
What can minimize engine effort and save fuel? Fuel consumption can be greatly reduced by accelerating the car gradually and by changing the gear very smoothly. By anticipating the stops, you can avoid applying sudden brakes. This can also be done by taking a long view of the road and coasting safely to where you […]
How does the heat transfer when the burner is lit?
How does the heat transfer when the burner is lit? The heat from the burner starts the molecules in contact with the burner start to move. Those molecules bump against others in the pot, which bump others, until all the molecules in the pot, including in the handle, are moving. When someone touches the pot […]
What is the purpose of rosin paper?
What is the purpose of rosin paper? When used as an inner liner in wall, roofing, or wood flooring applications, RED ROSIN PAPER acts as a separation barrier, protecting against wind and dust infiltration, while minimizing squeaks. It is compatible with coal tar and asphalt-based roofing systems. What is the difference between red rosin paper […]
How do you calculate the drag coefficient on a car?
How do you calculate the drag coefficient on a car? The drag coefficient Cd is equal to the drag D divided by the quantity: density r times half the velocity V squared times the reference area A. The drag coefficient then expresses the ratio of the drag force to the force produced by the dynamic […]
What polymers are used in rapid prototyping?
What polymers are used in rapid prototyping? ABS (Acrylonitrile Butadiene Styrene) is a general-purpose thermoplastic polymer, ABS performance characteristics: good rigidity, high impact strength, heat resistance, low temperature resistance, chemical resistance, mechanical strength and electrical performance, ease of processing, processing and dimensional … Which of the following is a type of material removal rapid prototyping? […]
Which is better Ferrari or Lambo?
Which is better Ferrari or Lambo? If you want one of the fastest street-legal cars in the world, a Lamborghini is the car for you. Lamborghini offers a similar semi-automatic transmission to Ferrari, but if you prefer to drive a manual, you should also go for a Lamborghini. Finally, Lamborghini produces less vehicles overall than […]
What distribution does the Student t distribution approach as the degrees of freedom become larger?
What distribution does the Student t distribution approach as the degrees of freedom become larger? The larger the degrees of freedom, the closer the t-density is to the normal density. This reflects the fact that the standard deviation s approaches for large sample size n. What happens to a T distribution as the sample size […]
How to find centroid using Pappus theorem?
How to find centroid using Pappus theorem? Figure 6. The volume of the solid of revolution can be determined using the 2nd theorem of Pappus: V=Ad. The path d traversed in one turn by the centroid of the ellipse is equal to. d=2πm. A=πab. V=Ad=πab⋅2πm=2π2mab. In particular, when m=2b, the volume is equal to V=4π2ab2. […]
What is the importance of patent law?
What is the importance of patent law? The Patent Rights enable the patent owners to recoup the manufacturing costs and obtain an ROI in the development of the patented technology. Without any second thoughts, proactive Patent Protection stimulates research and is a prime requirement for raising venture capital. What is patent drafting? Patent Drafting: Distinctly […]
