A biodiesel mixture consisting of 60 mol% methyl oleate (MO), 25 mol% methyl linoleate (ML), and 15 mol% methyl palmitate (MP) is held at 373.15 K and 200 MPa. Given PC-SAFT parameters: segment number \( m_i = [5.7, 6.3, 4.8] \), segment diameter \( \sigma_i = [3.95, 3.98, 3.91] \) Å, dispersion energy \( \epsilon_i/k = [260, 270, 250] \) K, and binary interaction parameters \( k_{ij} = 0.01 \), determine the isentropic speed of sound (m/s) using the PC-SAFT Helmholtz energy formulation and the thermodynamic identity\[c^2 = \left( \frac{\partial P}{\partial \rho} \right)_T + \frac{T \left( \frac{\partial P}{\partial T} \right)_\rho^2 }{ \rho^2 c_v },\]assuming the density is precomputed at 200 MPa and \( c_v \) is obtained from ideal mixing of pure-component values.
A steady Williamson nanofluid containing Cu nanoparticles flows over a permeable wedge with wall suction \( V_w = 0.015 \, \text{m/s} \), under a transverse magnetic field \( B_0 = 0.6 \, \text{T} \). The flow obeys the Buongiorno model, with \( D_B = 9 \times 10^{-10} \), \( D_T = 3.5 \times 10^{-8} \), and activation energy \( E_a = 65 \times 10^3 \). Hall and ion-slip effects are included with \( m_e = 0.4 \), \( \beta = 0.15 \). Thermal conductivity varies as \( k(T) = 0.6 (1 + 0.002 (T - 305)) \). Apply velocity and thermal jump conditions with \( \alpha_u = 0.9 \), \( \alpha_T = 0.8 \), \( \lambda = 2 \times 10^{-7} \). Using Keller’s method and similarity variables for wedge parameter \( m = 0.4 \), determine the entropy generation number \( N_s \) at \( x = 0.03 \), where \[N_s = \frac{k(T)}{T_\infty^2} \left( \frac{\partial T}{\partial y} \right)^2 + \frac{\mu}{T_\infty} \left( \frac{\partial u}{\partial y} \right)^2.\]
E. coli was continuously cultured in a continuous stirred tank fermenter with a working volume of 1 L by chemostat. A medium containing 4.0 g/L of glucose as a carbon source was fed to the fermenter at a constant flow rate of 0.5 L/hr, and the glucose concentration in the output stream was 0.20 g/L. The cell yield with respect to glucose was 0.42 g dry cells per gram glucose.

- A 0.45 mol/kg aqueous solution of 3-(methylamino)propylamine and 1-methylpiperazine (1:1 molar) flows at 0.5 g/s through a 2.5 m horizontal stainless steel coil (inner diameter 1.2 mm), entering at 358.15 K and 22 MPa and exiting at 20 MPa. A constant wall heat flux of 28 W is applied. Local density and isobaric heat capacity are obtained through from the Benedict–Webb–Rubin equation of state, with a 3% increase in heat capacity to account for wall sorption. Dynamic viscosity is obtained using the Green-Kubo relation with a given integral value of 2.1 × 10⁻¹⁰ Pa².s, and thermal conductivity is assumed constant. The local Nusselt number is corrected for thermal development using Nu(x) = 3.66 + (0.065 · Gz(x)^0.7) / (1 + 0.04 · Gz(x)^0.7), where Gz(x) = D · Re(x) · Pr(x) / x.

Antibiotic P is a compound secreted by microorganism A during the stationary phase. To produce P, substrate S is required. The growth of microorganism A follows the Monod equation, with a maximum specific growth rate $\mu_m = 1 h^{-1}$ and a half-saturation constant $K_s = 700\ mg/L$.The pilot process uses a chemostat with a working volume of $1000\ L$. In this chemostat, the outflow is processed to separate microorganisms, which are then concentrated tenfold and recycled. A sterile medium containing $15\ g/L$ of substrate is supplied at a flow rate of $100\ L/h$, while the recycled flow (concentrated) contains $5\ g/L$ and is also fed into the chemostat.Microorganism A yields $0.5\ g$ of biomass per $1\ g$ of substrate consumed $(Y^M_{X/S} = 0.5\ g\ A/g\ S)$, and its death rate $(k_d)$ is negligible.
