Question

. An air compressor cylinder has 15.0 cm bore and 15.0 cm stroke and

clearance is 5% of the stroke. The machine operates between 1.0 bar

and 5.0 bar. The polytropic index is 1.3 for both compression and

expansion processes. The compressor runs at 720 rpm with a

mechanical efficiency of 85%. Find the following: (i) Cylinder volume

at each corner of idealized indicator diagram in cm3 and (ii) Power

required driving the compressor​

Answer 1

Explanation:

the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
