What are three constraints that limit the design of a car

The answers are;

A car has to be designed with safety as the key factor. This reduces accidents and avoids company liability in case of accidents. The design of the bodies also has to ensure that the car reduces drag as it moves. This improves the car’s  performance and fuel economy. The cost of materials used to make the car also limit its design. The more expensive the material the less its used in the car design especially if the car is meant for the common market.

the awnser is group 12

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
