left 1:2 5:40 You are Dr. Evil speeding along in your 1967 Cooper diesel mini submarine at an evil 69 knots per hour with three minions, mini-me and your formerly fuzzy kitty cat, happily contemplating the launch of your T7 Fully-Armed Reek Targeting missiles and the ONE MILLION dollars you are certain to extort from them stuffy Brits. You have the snorkel up to pull in fresh air and exhaust the toxic diesel fumes emitted from your mini diesel electric generators. The snorkels are bringing in 200 liters per minute of fresh, outdoor air into the 2.438 m³ interior cabin of the sub and exhausting diesel fumes at the same rate. Annoyingly, mini-me, trying to eat your kitty cat, accidentally knocks over a mini missile, and it begins leaking, among other gasses, 0.02 mg/min of methyl mercaptan (foul, rotten cabbage smelling gas with an odor threshold of 0.002 mg/m³) into your completely mixed interior cabin. This continues this for the next eight minutes. You want to throw up. Provided the mass balance diagram below, and assuming that methyl mercaptan is a conservative pollutant and the sub is completely mixed, calculate the concentration of methyl mercaptan in the sub eight minutes after the leak begins. Q-200 240 200 V-2.438 m/ Select one: Oa. 0.112 mg/m³ b. None of the other answers are correct c. 0.048 mg/m³ O d. Cannot be determined with the information provided e. 0.028 mg/m³

According to the experiments, the change in entropy of 200 g of water when heated from an unknown temperature to 90 ⁰C at constant pressure is 250 J/K. Cp of water, assumed to be constant throughout the process, is 4.186 J/g-K. Determine the initial density of water (in kg/m³) before it was being heated. Density of water at different temperatures is presented (use this table only). Answer Format: [2 decimals]

A rigid insulated tank is divided into 2 equal compartments by athin rigid partition. One of the compartments contains air, assumedto be an ideal gas at 800 kPa and 300 K. The other compartment isunder a vacuum. The partition is suddenly broken and the air rushesinto the evacuated compartment. The tank pressure and temperatureeventually equilibrate. (a) define the system you will use and draw a labeled schematic.(b) write the energy balance for the system, making simplificationsas appropriate(c) what is the final temperature of the gas, K?(d) what is the final pressure, kPa?(e) To calculate the entropy change of the process, you need to definea reversible path from the initial state to the final state. What isthat path?(f) What is ∆ssys for the process.(g) To calculate the entropy change of the surroundings, you needto define a reversible path from the initial state to the final state.What is that path?(h) What is the entropy change of the surroundings. ∆ssurr(i) What is the total…

A pressurized tank of water has a 10-cm diameter orifice at the side bottom corner of the tank, where the water is being discharge to the atmosphere. The water level is 3 meters above the orifice. The tank air pressure above the water level is 300 kPa. Neglecting frictional effects, the initial discharge rate of water in kilograms per second (kg/s) from the tank is
