Two liters of a liquid chemical is spilled on the laboratory floor. Assume 1 atm of pressure and a temperature of 25°C. a. If the center of the liquid pool is 2 mm deep, calculate the area of the pool. b. What ventilation rate, in m3/s, is required to prevent the air concentration from exceeding the TLV for the chemical of 100 ppm? c. Ventilation air is provided for the lab via a 0.5-m2 duct. The air velocity exiting the duct is measured with a velometer at 30 m/s. Calculate the volumetric flow of air from this duct in m3/s. Is this adequate ventilation for this spill?

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
