Solution:
Given:
pressure ratio, = 6.75
Formula used:
(1)
where,
= pressure ratio
γ = specific heat ratio of a gas( here, helium gas it is 1.667)
Now,
Eqn (1 ) is for thermal efficiency of an ideal gas, using eqn (1), we get
\eta = 1- \frac{1}{2.1469} = 0.5342
percentage thermal efficiency, \eta =53.42%
The expression of V(m³)=e^(t(s)) to make V in in³ and t in minutes is;
V(in³) = (¹/₆₁₀₂₄)a
We are given that;
Volume of microbial culture is observed to increase according to the formula;
V = e^(t)
where;
t is in seconds
V is in m³
We want to now express V in in³ and t in minutes.
Now, from conversions;
1 m³ = 61024 in³
Also; 1 second = 1/60 minutes
according to formula for exponential decay, we know that;
V = ae^(bt)
Thus, we have;
61024V = ae^(¹/₆₀b(t(h))
V(in³) = (¹/₆₁₀₂₄)a
