assuming it is pure copper and not an alloy, 17(k), 9.3 Co
It means the various parts of the item are joined with rivets made of brass or bronze. Often brass or bronze rivets are a decorative item.
In dray expansion evaporator, the liquid refrigerant is generally fed by an expansion valve. the expansion valve controls the rate of flow of refrigerant to the evaporator. In the evaporator the liquid refrigerant is vaporized and superheated by the time it reaches to the end of evaporator. At inlet of the evaporator, the refrigerant is predominantly in the liquid form with a small amount of vapor formed as a result of flashing at the expansion valve. the liquid refrigerant passes through the evaporator, more and more refrigerant is vaporized by the load. according to the load, the liquid will come into evaporator and vaporize and reaches to superheat at the end of the evaporator. The inside of the evaporator is far from dry but wetted with liquid so named as dry expansion evaporator.
It is between .35 to .45 per ounce. It will depend on the amount of brass in the item and what item you have.
Linear thermal expansion (α): Iron - 11,8.10-6/°C Aluminium - 23,1.10-6/°C Copper - 17.10-6/°C Brass - 19.10-6/°C See the link below for a more complete table.

What is today's rate of Brass per Kg. in hyderabad
Brass and iron have different coefficients of thermal expansion, so when exposed to a change in temperature, they would expand by different amounts. This difference in expansion causes the bimetallic strip to bend due to the unequal expansion of the two metals.
When heated, a bimetallic strip made of iron and brass will bend towards the brass side due to the different coefficients of thermal expansion of the two metals. This is because brass expands more than iron when heated, causing the strip to curve towards the side with greater expansion.
The coeifficent of expansion per degree can be found in the manufacturers charts
rs 500
Linear Temperature Expansion Coefficient (10-6 in/in oF) Brass = 10.4 Steel = 7.3 Therefore brass will expand or contract more steel.
repossession
Brass expands roughly 1.6 times more than iron when heated to the same temperatures.
No, the brass rod could be expanding or contracting due to changes in temperature, but it does not necessarily mean that brass shrinks on heating. Temperature changes can cause thermal expansion or contraction in materials, including brass. To determine if brass specifically shrinks on heating, a controlled experiment measuring thermal expansion coefficients would be needed.
A good data transfer rate for a PCI expansion card is between 200 and 400mbps.
