What is reheating in Rankine Cycle? Reheating is a method of improving Rankine cycle efficiency which consists of inter-stage heating of the expanding steam. After the first stage of expansion which typically reduces initial steam pressure by one-fourth, the steam is heated up (or close) to the maximum heat source temperature. What is regeneration in […]
What does radial velocity tell us?
What does radial velocity tell us? A positive radial velocity indicates the distance between the objects is or was increasing; a negative radial velocity indicates the distance between the source and observer is or was decreasing. How does radius affect velocity? In this case, again, velocity increases as radius is decreased, but to do that […]
What Is percent finer in sieve analysis?
What Is percent finer in sieve analysis? “% Finer” represents the percentage of material of the total sample (100%) that will pass through the current sieve. How do you find the D10 D30 D60 from the grain size distribution curve? The particle diameters defining 10%, 30%, and 60% finer from the grain-size distribution curve are […]
What is the function of shock absorber?
What is the function of shock absorber? The role of the shock absorber is to keep the car’s tyres in permanent contact with the road, helping to provide optimum grip, when cornering and braking. Shock absorbers are part of the suspension, so if the shocks are worn, the vehicle’s ride and comfort is compromised. How […]
How do capacitors boost voltage?
How do capacitors boost voltage? because capacitors store energy, they can increase the apparent voltage in some circuits. Capacitors can reduce peak power demands on power sources by providing stored energy during peak loads, which would cause a voltage drop in the power source. Do capacitors decrease voltage? A capacitor opposes changes in voltage. If […]
What are the 3 levers involved in deep squat?
What are the 3 levers involved in deep squat? The levers that exist in this analysis are the back, the femur, and the shank or lower leg. The levers, as they hinge around the hip and knee joints, form the diagnostic angles used to analyze and discuss the movement. What are examples of second class […]
What are the 3 factors that cause accidents?
What are the 3 factors that cause accidents? Cause factors can be grouped into the following categories: human factors/personnel error. malfunction or failure of aircraft structures, engines, or other systems. deficient maintenance. hazardous environment involving weather, volcanic ash, birds, etc. air traffic management errors. any combination of the above. What are the 5 lab safety […]
When 1kg of ice at 0c is mixed with?
Can we see polarized light?
Can we see polarized light? Though most of us are unaware of our capacity to do so, humans can also perceive the polarization of light. We detect the orientation of polarized light using ‘Haidinger’s brushes’, an entoptic visual phenomenon described by Wilhelm Karl von Haidinger in 1844 [2]. How can you tell if light is […]
Do transverse waves need a medium?
Do transverse waves need a medium? Transverse waves require a relatively rigid medium in order to transmit their energy. What are transverse waves give examples too? Transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave’s advance. Surface ripples on water, seismic S […]
