Engineering Thermodynamics The expansion ratio (r) is the ratio of (where v1 = Volume at the beginning of expansion, and v2 = Volume at the end of expansion) (v1 + v2)/v1 v1/v2 (v1 + v2)/v2 v2/v1 (v1 + v2)/v1 v1/v2 (v1 + v2)/v2 v2/v1 ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics Carbonization of coal consists of Heating the wood with a limited supply of air to temperature not less than 280°C Drying and crushing the coal to a fine powder Moulding the finely ground coal under pressure with or without a binding material None of these Heating the wood with a limited supply of air to temperature not less than 280°C Drying and crushing the coal to a fine powder Moulding the finely ground coal under pressure with or without a binding material None of these ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics For a perfect gas, according to Boyle’s law (where P = Absolute pressure, V = Volume and T = Absolute temperature) P v = constant, if T is kept constant T/P = constant, if v is kept constant P/T = constant, if v is kept constant V/T = constant, if p is kept constant P v = constant, if T is kept constant T/P = constant, if v is kept constant P/T = constant, if v is kept constant V/T = constant, if p is kept constant ANSWER DOWNLOAD EXAMIANS APP
