Answer to Question #156234 in English for Ali

Question

Under standard conditions a certain gas weighs 0.14 lb / ft³ . Calculate its density , specific volume , and specific gravity relative to air weighing 0.075 lb / ft³ ?

Answer 1

Answer:

Specific weight of gas γ gas =0.14 lb/ft³

Specific weight of air γ air =0.075 lb/ft³

Acceleration due to gravity g=32.2 ft/s²

claim- to find density, specific volume, specific gravity

density of gas= $specific weight of gas \over the gravitational acceleration$

substitute the values

density of gas= $0.14 \over 32.2$

                    =0.00435 slugs/ft³

specific volume =reciprocal of density

γ gas = $1 \over ρ gas$

substitute the value

Υ gas = $1 \over 0.00435$

      =229.88 ft³ /slug

specific gravity= $specific weight of gas \over specific weight of air$

substitute the values

specific gravity= $0.14 \over 0.075$

                      =1.866
