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 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. 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.

Consider the two separate sets of measured data for a silt-loam soil measured by Mualem (1976): (1) suction versus water content, and (2) suction versus relative permeability of unsaturated soil, k/ks. Assume that 0s 0.396, 0res = 0.131, and Ks=5.74×10-7 m/s. a. Using the method of least squares in Excel, compute the best-fit values for αNG (kPa¹) and nvg for the van Genuchten (1980) relationship for data set # 1 (assume m = 1-1/nvG). See the example spreadsheet in the homework folder under the files section of Canvas for help in performing this calculation. b. Repeat part (a) and estimate the λ and ac parameters for the Brooks and Corey (1964) SWRC for data set #1. Note that you may need to include an "if" statement at the air entry suction. c. Plot the data for the SWRC versus the fitted van Genuchten (1980) and Brooks and Corey (1964) curves. Which relationship matches the capillary pressure data better (BC or VG)?
