Select the term which best describes the following scenario. Researchers are investigating a gluten-free diet and are providing all meals to participants. The participants are not told if their meals contain gluten. The researchers studying the impact of the diet also do not know which subjects have been given the meals containing gluten.

3. (25 Points.) (a) Calculate the work done by the vector field $\vec{F} = (2xyz^3)\vec{i} + (x^2z^3 + 2yz)\vec{j} + (3x^2yz^2 + y^2 + 3)\vec{k}$ in moving a particle along straight line segments from (0, 2, 1) to (-1, 2, 4), to (3, 0, 0), to (4, 0, -1). (b) Calculate the work done by the vector field $\vec{F} = (y + e^{\sin x})\vec{i} + 2x\vec{j}$ in moving a particle along the curve $y^2 = x$ from (9, -3) to (9, 3).

A liquid mixture of methanol (CH3OH, Molecular Weight: 32 g/mol) and ethanol (CH3CH2OH, Molecular Weight: 46 g/mol) containing 50.0 wt% methanol at 95.0°C and pressure Po atm is fed at a rate of 60 m³/h into a heated flash tank maintained at a pressure Ptank << Po. When the feed is exposed to the reduced pressure in this unit, a portion of it evaporates. The liquid and vapor product streams are in equilibrium at 60.0°C and Ptank. The liquid product contains 50 mole% methanol. When carrying out the requested calculations, assume volume additivity of liquid methanol and ethanol, use Raoult's law and the chart below where necessary, and neglect the effect of pressure on enthalpy. 95°C 2.92 atm 1.87 atm 60°C 0.84 atm 0.46 atm Pmethanol Pethanol 1. Calculate the molar flow rate (mol/s) and molar composition (component mole fractions) of the feed stream. Then calculate the minimum value of Po (atm) needed to keep the feed stream in the liquid state until it enters the flash tank. (10 points) 2. Calculate Ptank (atm), the mole fraction of methanol in the vapor, and the molar flow rates of the liquid and vapor products. (10 points) 3. Calculate the required heat input rate in kilowatts using the following heat capacity data. (10 points) Liquid: Cp,methanol = 0.085 + 8.3 × 10^5 T Cp,ethanol = 0.043 + 1.6 × 10^4 T Vapor: Cp,methanol = 0.155 + 8.3 × 10^5 T Cp,ethanol = 0.061 + 1.6 × 10^4 T
