Hot-wire anemometer is most well known thermal anemometer, measure fluid velocity by nothing the heat convected away by the fluid. Hot-anemometers are popular for unsteady flow of gas and liquid flow measurement. The basic system consists of electrically heated wire suitably is liquid.
Due to the change in velocity of flowing liquid the heat lost by the wire also changes. The loss in temperature causes the change in resistance of a hot wire. And this changes the current through the hot wire for a constant voltage. Flow can be measured by measuring the change in the resistance or current.

Strain energy stored within the elastic limit is called resilience.
By the principle of work, the amount of strain energy in a body is found.
When a load acts on a body there will be deformation, which causes movement of the applied load. This work is done by the applied load.

Turn Down or Turn down Ration describes the range of flow rates between maximum and minimum flow over which a flow meter will work satisfactorily within the accuracy limits and repeatability of tolerances specified by the manufacturer.
Flow meter Turn Down = Maximum Flow/Minimum Flow.

Tolerance: The term tolerance refers to the difference between the upper (maximum) limit and lower (minimum) limit of a dimension. In other words, tolerance is the maximum permissible variation in a dimension.

A thrust bearing supports the load, which acts along the axis of the shaft

A rivet joint failure normally occurs by any one pr combination of the following
1.Tearing of the plate at edge
2.Shearing of the rivets or plate at edge
3.Crushing of the rivets or plate

We know KVA is directly proportional to frequency.
Here frequency halved, so kVA will be half of given, ie; 200kVA

Carbon fibre is used due to its light weight and high strength

Skim bob prevents the slag and dirt which floats on the top of molten metal and allows only clean metal underneath to pass

Since riser acts as a reservoir of molten metal to mould cavity , it is so designed as to freeze after the casting freezes
