Why do we use physical balance?
A physical balance can be used to measure both mass and weight of an object.
How sensitive is a physical balance?
A physical balance is a very sensitive common balance which can measure weights in milligram order. It is placed in a protective glass case so that even dust and wind can’t affect the accuracy of the instrument.
What is meant by physical balance?
In simple terms a physical balance is a weighing instrument which helps in measuring the mass of a substance or more specifically the gravitational mass of the substance.
Is physical balance is more sensitive than beam balance?
Explanation: Physical balance is very sensitive and used in labs for measuring. It is similar to beam balance. It can measure small differences in mass up to milligram.
What is the least count of physical balance?
Expert Answer:
- Least count of a measuring instrument is the least value of physical quantity that can be measured accurately using the instrument.
- For example,
- Take a spring balance whose range is 0-25kg.
- Measurement=1kg.
- Number of divisions=10.
- Least count=1/10 =0.1kg or 100g.
What is range and least count?
The least count is related to the precision of an instrument. Basically, An Ammeter has a range of 0−3A and there 30 divisions on the ammeter. Range is basically the difference between maximum value to the minimum value. So the range of ammeter =3-0= 3 A.
What is mean by least count of balance?
Answer: To weigh 10 mg sample you have to use 10X0. 1% = 0.01 mg least count balance. It shows that if you have a balance with least count 0.01 mg, you can weigh minimum 10 mg sample on it.
How do I calculate least count?
The formula of Vernier calliper least counts is determined by dividing the smallest reading of the main scale with the total number of vernier scale divisions. The LC of vernier calliper is the difference between one smallest main scale reading and one smallest vernier scale reading of 0.1 mm 0r 0.01 cm.
What is least count of scale?
Least count of a measuring instrument is the smallest measurement that can be made accurately with the given measuring instrument. A metre scale normally has graduations at 1 mm (or 0.1 cm) spacing, as the smallest division on its scale.
What is the uses of screw?
The most common uses of screws are to hold objects together — such as wood — and to position objects. Often screws have a head on one end of the screw that allows it to be turned. The head is usually larger than the body of the screw.
What are examples of screw?
Some examples of the uses of a screw are in a jar lid, a drill, a bolt, a light bulb, faucets, bottle caps and ball point pens. Circular stairways are also a form of a screw. Another use of the screw is in a device known as a screw pump.
What is the working principle of screw compressor?
The basic principle of a screw compressor is as the male and female rotors are rotating in opposite direction they draw air in between them. As the air progresses along the rotors the air is compressed as the volume space between the rotors decreases, hence creating compressed air that is displace to the outlet.
What is the principle of centrifugal compressor?
A centrifugal compressor imparts kinetic energy into the airstream by increasing the velocity of the air using a rotating element and then converts this kinetic energy into potential energy in the form of pressure.
Why oil is used in screw compressor?
Oil-lubricated screw compressors Oil-lubricated rotary screw compressors, inject oil into the compression chamber. This oil cools and lubricates the compressor element. It also helps to remove the heat from the compression process, and aids minimising leakage in the compression chamber.
What is screw compressor and how it works explain in details?
Working Principle of a Screw Compressor. The oil injected rotary screw compressor is a positive displacement type compressor. A given quantity of air or gas is trapped in a compression chamber and the space that it occupies is mechanically reduced, causing a corresponding rise in pressure prior to discharge.
What is compressor and its types?
The four most common types of air compressors you will see are: Rotary Screw Compressor. Reciprocating Air Compressor. Axial Compressor. Centrifugal Compressor.
What are the advantages of a screw compressor?
Advantages Screw Compressors Compared to Piston Compressors:
- Screw compressors have 25 to 30 percent higher energy efficiency than piston compressors.
- Screw compressors have a lot less noise and vibration than piston compressors.
- Screw compressors occupy less space than piston compressors.
What is screw type chiller?
Screw Chiller A screw chiller is a liquid chiller that uses two rotating helical screws to provide the needed pressure to drive the vapor-compression refrigeration process. Screw chillers are more compact, quieter and contain fewer parts than their alternatives: reciprocating, centrifugal and absorption chillers.
What are the two basic types of chillers?
Chillers fall under two main categories: vapor compression and vapor absorption chillers.
What is difference between centrifugal and screw chillers?
Centrifugal compressors have better full-load efficiency, and screw compressors can achieve comparable part-load efficiencies. Screw compressors are also better for part-load applications because they’re stable down to about 10% capacity, whereas centrifugal compressors can begin to surge at about 20% to 40% capacity.
