Suppose a tanker truck, carrying a concentrated solution of sodium hydroxide destined for a pulp and paper company, crashes on the highway. Should this dangerous chemical spill be neutralized or diluted? Discuss the pros and cons for each proposed solution.

A steady-flow Carnot refrigeration cycle uses refrigerant-134a as the working fluid. The refrigerant changes from saturated vapor to saturated liquid at 40 C in the condenser as it rejects heat. The evaporator pressure is 120 kPa. Determine: (a) the amount of heat absorbed from the refrigerated space; qL = _______________ kJ/kg (b) the net work input; and wnet = ______________ kJ/kg (c) the coefficient of performance of the system. COP = _____________

An Otto cycle having a compression ratio of 7:1 uses air as the working fluid. Initially p1 = 95 kPa,

T1 = 17 C, and V1 = 0.0038 m

. During the heat addition process, 7.5 kJ of heat are added.

Determine:

(a) the heat rejected Q4-1 = __________ kJ

(b) the net work of the cycle Wnet = ________________ kJ

(c) the cycle thermal efficiency η = ________ %

(d) the mean effective pressure. MEP = __________ kPa

•Describe the consequences of performing a kinetics study with too wide a temperature range for a diffusion dominated failure mechanism? What errors would be caused?

Air enters a counter-flow drier at 70˚C dry bulb temperature and 20˚C dew point temperature. Air leaves the drier at 40˚C and 60% relative humidity. The initial moisture content of the product is 82% (wet basis). The amount of air moving through the drier is 2000kg of dry air per hour. The mass flow rate of the product is 10kg dry solid per hour. What is the final moisture content of the dried product in wet basis?

A continuous fractionating column operating at atmospheric pressure, is to be designed to separate a mixture containing 40% carbon disulfide (CS₂ ) and 60% Carbon tetra chloride (CCl₄ ) into an overhead product containing 95% w.w CS₂ and 97% CCl₄ waste. (All weight percent).

Complete the material balance around the column? All results should be in mole and mole percent (Not in weight percent).

1. Draw a process flowchart

2. Write balances around the column based on CS₂ and CCl₄.

3. Determine the expected mole fraction and mole flow rate for all streams; feed, top and bottom of the column.
