Answer:
Pressure = 610.125 kPa
Explanation:
Given:
Mass of the air, m = 0.3 kg
Volume of the cylinder, V = 42.9 litres = 42.9 × 10⁻³ m³
R value for the air = 287 J/kg/K
Temperature, T = 31.0° C = 304 K
Now,
we know the ideal gas equation is given as :
PV=mRT
where,
P is the pressure
on substituting the values, in the above formula
we get
P × 42.9 × 10⁻³ = 0.3 × 287 × 304
or
P = 610125.87 Pa
or
P = 610.125 kPa

See explaination
Explanation:
Lets first consider the term Isentropic efficiency. The isentropic efficiency of a compressor or pump is defined as the ratio of the work input to an isentropic process, to the work input to the actual process between the same inlet and exit pressures. IN practice, compressors are intentionally cooled to minimize the work input.

Answer:
the estimated time of submersion is 17.7 years
Explanation:
Given the data in the question;
estimate the time of submersion in years.
we write down the relation between time of submersion and corrosion penetration as follows;
CPR(mpy) = K × W(mg) / [ A(in²) × p(g/cm³) × t(hr) ]
we solve for t
t = (K × W) / ( AP × CPR )
given that;
Area A = 5 in²
W = 2.3 kg = 2.3 × 10⁶ mg
density of steel p = 7.9 g/cm³
CPR = 200
we know that K is 534
so we substitute
t = (534 × 2.3 × 10⁶ mg) / ( 5 in² × 7.9 g/cm³ × 200 mpy )
t = 1,228,200,000 / 7900
t = 155468.3544 hr
t = 155468.3544 hr × ( 1 yrs / ( 365 × 24 hrs )
t = 17.7 years
Therefore, the estimated time of submersion is 17.7 years
