In the published paper, "Exergy-based Greenhouse gas metric of buildings", use the value of the Exergy Loss of Emission of carbon dioxide to evaluate the index value for 1000 occupants for 50 years building life span in kilogram per person per year
A CO₂-saturated brine (ionic strength = 2.5 mol/kg, pH = 3, a_H⁺ = 0.01) flows at 2 cm/s through a horizontal tubular reactor (L = 1 m, D = 0.05 m) packed with 5 kg of olivine (Zhuravlev-BET surface area = 30 m²/g). The system operates at 90 °C and 40 bar, and external mass transfer resistance is negligible. The rate-limiting step is electron transfer at the mineral surface, governed by Marcus theory, with λ = 0.75 eV, ΔG° = –0.30 eV, and k₀ = 10⁶ s⁻¹. The Mg²⁺ activity coefficient is γ = 0.76 (from PHREEQC with Pitzer model). For Mg₂SiO₄ + 4 H⁺ → 2 Mg²⁺ + SiO₂(aq) + 2 H₂O, determine the total moles of Mg²⁺ released after 10 minutes at steady state.
In baseball, batters frequently attempt to hit a ball as far as possible. However, baseballs are inelastic with an officially required "coefficient of restitution" CR ≈ 0.55 on ash wood. The coefficient of restitution of a dropped ball iswhere H is the initial drop height, h is the max. height on the rebound, and h ≈ 2πH tan δ for a homogeneous material. Assuming that a baseball is homogeneous and has a storage modulus approximately the same as that of cork (E' = 18.6 MPa), what must the value of the loss modulus E'' be so that the ball is regulation?

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.

- A pilot process is being planned to produce antibiotic P. 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. Additionally, $1\ g$ of microorganism A produces $0.05\ g$ of antibiotic P per hour $(q_P = 0.05 g\ P/h\cdot g\ A)$, and $1\ g$…arrow_forwardIn the production of ethyl acetate via reactive distillation, the column operates at 5 bar with an equimolar feed (ethanol + acetic acid) at 80°C.
