Will a ball bounce higher if dropped on tile or carpet?
Tile since loss of energy due to collision will be less compared to that on carpet.
What is insensible heat?
Also Latent Heat Loss. The heat that is lost through the continuous, unnoticed water loss that occurs with vaporization accounting for 10% of basal heat production. Evaporation accounts for the greatest heat loss when body head increases.. Does not result in temperature increase of surrounding air.
Will a ball bounce higher if it is dropped from a greater distance?
Depends on if the object has reached it terminal velocity. From an energy standpoint, yes, as long as there is no appreciable loss of energy due to friction. From a common sense standpoint, it will also bounce higher.
What is the heat escape lessening position designed to prevent?
in boating the heat escape lessening position is designed to prevent?
Difference between coaxial cable and wave guide?
Waveguides are used at higher frequencies where their loss is lower than coaxial cable. Coaxial cable is used at lower frequencies where waveguides are too large and heavy. Lastly Coaxial cable is also used at higher frequencies where some flexibility is required.
Would a laminar flow element a venturi a flow nozzle or an orifice plate produce the smallest total head loss?
The lowest head loss is from a venturi since it has the lowest coefficient of discharge. typical coefficients range from 0.95-0.99 where the higher coefficient is directly proportional to larger square root of Reynolds number.
What is the order of efficiency of venturi meter orifice meter and rotoameter?
The orifice plate can easily be changed to accomodate widely different flow rates, whereas the throat diameter of a venturi is fixed, so that its range of flow rates is circumscribed by the practical limits of Dp.The orifice meter has a large permanent loss of pressure because of the presence of eddies on the downstream side of the orifice-plate; the shape of the venturi meter prevents the formation OS these eddies and greatly reduces the permanent loss.The orifice is cheap and easy to install. The venturi meter is expensive, as it must be carefully proportioned and fabricated. A home made orifice is often entirely satisfactory, whereas a venturi meter is practically always purchased from an instrument dealer.On the other hand, the head lost in the orifice for the same conditions as in the venturi is many times greater. The power lost is proportionally greater, and, when an orifice is inserted in a line carrying fluid continuously over long periods of time, the cost of the power may be out of all proportion to the saving in first cost. Orifices are therefore best used for testing purposes or other cases where the power lost is not a factor, as in steam lines.However, in spite of considerations of power loss, orifices are widely used, partly because of their greater flexibility, because installing a new orifice plate with a different opening is a simpler matter. The venturi meter can not be so altered. Venturi meters are used only for permanent installations.It should be noted that for a given pipe diameter and a given diameter of orifice opening or venturi throat, the reading of the venturi meter for a given velocity is to the reading of the orifice as (0.61/0.98)2, or 1:2.58.(i.e. orifice meter will show higher manometer reading for a given velocity than venturi meter).
Tell me the main uses of venturi meter?
The discharge coefficient is near unity and Non-recoverable net head loss is very small.
What is the calibration curve of orifice meter?
The calibration curve for an orifice meter will depend on the size of the orifice, the size of the pipe and the pressure loss over the meter. Typical calibration curves have pressure (or head) loss on the vertical (y) axis and flow rate on the horizontal (x) axis.
A power loss occurs when you apply carburetor heat because?
The flow of air in the carburetor venturi is restricted.
What happen to the Head Loss of Water if the diameter of the pipe increases?
Head loss will decrease
Why uplink frequency is kept higher than downlink freqquency in satellite communication?
due to path loss : higher is the frequency higher is the patrh loss
Living in areas of higher altitude increases fluid loss?
Living in areas of higher altitude can increase fluid loss. Individuals in higher elevations will need to increase their water intake to compensate for this loss.
Can loss of consciousness lead to loss of memory?
It depends upon whether they hit their head or not. A bump to the head can cause memory loss. Another cause of memory loss is stress or anxiety.
Applications of venturimeter?
1. It is used for flow measerment with minimum head loss. 2. It is used in industries for flow measerment of chemicals. 3. it is also used in the airoplane for measurment of speed of plane.
What is coefficient of percolation?
percolation coefficeint is loss of head* loss of creep.
What is percolation coefficient?
percolation coefficeint is loss of head* loss of creep.
