You are working on an air conditioning system. A roll of cylindrical copper tubing has an outside diameter of 78 7 8 inch and an inside diameter of 34 3 4 inch. How much refrigerant can 12 feet of the tubing hold?.

Sagot :

557,568 inch³ of refrigerant can be held by the tubing.

Here we have to find how much a refrigerant can hold.

Data given:

outer diameter (d) = 78inch

outer radius(r) = 39 inch

inner diameter (d') = 34 inch

inner radius (r') = 17inch

Height (h) = 12 feet

= 12 × 12

= 144 inch

the formula to find the volume of the cylinder:

volume= пr²h

So here we get

Refrigerant hold = Volume of the outer cylinder - the volume of the inner cylinder

= πr²h - πr'²h

= πh(r² - r'²)

= π ×144 ( 39² - 17²)

= π × 144 ×56 × 22

= 22/7 × 144 × 56 × 22

= 557,568 inch³

Therefore the refrigerant can hold 557,568 inch³.
