Question

if the required pressure in the tyre of a car is 199kPa, then what will be the (a) gauge pressure and (b) absolute pressure?​

Answer 1

Answer:

(i) Gauge pressure

${ p }{ g }$ = 190 k Pa

(ii) Absolute pressure

p = ${ p }{ a }$ +

${ p }_{ g }$ = 101k Pa + 199k Pa = 300k Pa

Answer 2

Given:

The required pressure in the car = 199 k pa

To Find:

 absolute pressure and gauge pressure

Explanation:

Let P be absolute pressure

(i) Gauge pressure

  = 199 k pa

(ii) Absolute pressure

P - P(a) = P(g)

P = p(a) + p(g)

  = 101 k pa + 199 k Pa

  = 300 k pa

Answer = 199k pa , 300 k pa
