A stream of air at 35°C and a gauge pressure of 0.5 atm (Stream 1) flows into a pipe passing through a heater, emerges at 87°C and 0.2 atm (gauge), and splits into two streams. Stream 2 passes out of the system, and Stream 3 goes through another heater and emerges at 180°C and 0.1 atm (gauge). Flowmeters mounted in all three streams show readings of 3120 L/min (Stream 1), 1940 L/mm (Stream 2), and 3420 L/min (Stream 3).
(a) Show that the system is not functioning properly.
(b) Speculate on several possible causes of the malfunction, and state how you would check each one.

- Biogas system design for cooking for a family of 9 members is considered here. The system design includes the estimation of total gas required, amount of feedstock (or dung), required and the number of animals required to have feedstock of a given amount. Following assumptions are made for the design: 1- About 350-450 liters of biogas required per day per person for cooking (in engine about 450 liters/hp/hour of biogas is required) 2- Average production of dung per animal per day: (Cow:10 kg/day, Bullock:14 kg/day and Buffalo:15 kg/day) 3- Other assumptions are: 1000 liters of gas is equivalent to 1 m3 of gas, average gas production from dung is about 40 liters/kg of fresh dung and retention period of dung slurry in digester is 50 days.

This device consists of a glass bulb forming one end of a beam, the whole surrounded by a closed container. The beam is pivoted, and the balance point is attained by raising the pressure of gas in the container, so increasing the buoyancy of the enclosed bulb. In one experiment, the balance point was reached when the fluorocarbon pressure was 327.10 Torr; for the same setting of the pivot, a balance was reached when CHF, (M= 70.014g mol) was introduced at 423.22 Torr. A repeat of the experiment with a different setting of the pivot required a pressure of 293.22 Torr of the fluorocarbon and 427.22 Torr of the CHF,. What is the molar mass of the fluorocarbon?

- 2-4. Gasoline vapors are vented to the atmosphere when an underground gasoline storage tank is filled. If the tanker truck discharges into the top of the tank with no vapor control (known as the splash fill method), the emission of gaso- line vapors is estimated to be 2.75 kg/m' of gasoline delivered to the tank. If the tank is equipped with a pressure relief valve and interlocking hose connec- tion and the tanker truck discharges into the bottom of the tank below the surface of the gasoline in the storage tank, the emission of gasoline vapors is estimated to be 0.095 kg/m of gasoline delivered (Wark et al., 1998). Assume that the service station must refill the tank with 4.00 m' of gasoline once a week. Draw a mass balance diagram and estimate the annual loss of gasoline vapor (in kg/y) for the splash fill method. Estimate the value of the fuel that is captured if the vapor control system is used. Assume the density of the con- densed vapors is 0.800 g/mL and the cost of the gasoline…arrow_forwardUse yourresearch skill to find out the size onethree cylindrical tank, on Petrojam tankfarm.
