please help with part b for both

TOT Reduce the fears of the lawyers. A-3 a. Which of the following is not part of inherent safety? simplify b. moderate substitute d. control minimize c. e. B. About100 workers in a gas processing plant are exposed to the following concentrations of phosgene gas for the indicated hours. 2.2 ppm for 2.75 hr b. 1.5 ppm for 3.00 hr 0.1 ppm for 2.25 hr 2. e. To determine the potential fatalities, there are two approaches to interpret the problema: () assume the same workers exposed over 8-17 (2.75 +3.00 +2.25 period, and sume cachexposure is separate fie independent and isolated event) with diferent workers Using the Probit Egn. 2-5 (Textbook) y = klucz, warm ppm and V in min with b = -19.27. and = 3:69. determine the potential the Woods articulated above ti & it). Briellytnicitet your results obtained by the method O A-2 exposure d. only a 40 hour exposure When filling a container with liquid, the fundamental processes that occur are: mass transfer only b. displacement of the gas by the liquid only. both mass transfer and displacement of the gas by the liquid. a. c. A-3 a. A 10,000 liter vessel is filled with a liquid solvent at a rate of 50 liter/min. filling time and constant filling rate are 20 min and 5.0 x 10 min respectively b. filling time and constant filling rate are 50 min and 2.0 x 10 min, respectively filling time and constant filling rate are 100 min and 1.0 x 10 min respectively d. filling time and constant filling rate are 200 min and 5.0 x 10 min, respectively c. B. A worker splash fills hexane (MW: 86.18: TLV-TWA: 50 ppm) into a 2642-gallon fi.e., 10 m volume) vessel through a 10-cm diameter filling hole. It takes about 2 hr to fill the vessel at a constant filling rate. The local ventilation rate is 150 m'min, the ambient pressure and Temperature are 1 atm ( 760 mm-Hg) and 25C. respectively. Assume average non-ideal mixing factor k for the ventilation condition. The vapor pressure of hexane can be estimated using Antoine equation with the given constants: B In(P) = A - where T is in K and Psat is the saturation pressure (mm Hg) C+1 Antoine constants for hexane A = 15.33GG. B=2697.36 and C = -18.78 Estimate the local concentration of the hexans om What observations you can make reading sure to be ane
