(a)
Interpretation:
Calculate the number of cans required to apply paint on the tunnel.
Concept introduction:
It is given that a spray can holds nine fluid ounces and has the capability to cover an area of approximately 25 ft2.
The tunnel is 8 feet wide, 12 feet high and 148 feet long.
Assume the tunnel is rectangular.
(b)
Interpretation:
List top three hazards that might encounter during the project and suggest safety precaution for each hazard.

Material Safety Data Sheet (MSDS) is a s a document that contains information on the potential hazards (health, fire, reactivity and environmental) and how to work safely with the chemical product. Therefore, MSDS can be used to answer this question.

- In a multi-stage distillation column designed to separate a binary mixture of ethanol and water, the mass flow rate of the feed entering the column is \( F \), and the distillate product flow rate is \( D \). The reflux ratio \( R \) is defined as the ratio of the liquid returned to the column to the distillate flow rate. For the ideal case, where the column operates at maximum efficiency, determine the **minimum reflux ratio** \( R_{\text{min}} \) when the relative volatility \( \alpha = 1.5 \).arrow_forwardQ2: Draw the layout of a basic asynchronous 32k * 8 SRAM.arrow_forwardA distillation column with 100 kmol/h feed of 50% A and 50% B produces a distillate product with xD = 0.95 and a bottom stream with xbot = 0.04 of the more volatile species A.

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)?
