5-28 the following data are from the u. s. epa ap-42 emission factors for malt beverages. for a steam-heated brewers grain dryer, co 5 0.22, co2 5 53, and voc (ethanol) 5 0.73. the units for the emission factors in the epa tables are in lbs of pollutant per 1,000 barrels (bbl). a brewery produces about 7 million barrels of product per year. estimate the emissions of

(a) kg of carbon monoxide per year from fermenter venting
(b) kg of carbon dioxide per year from fermenter venting
(c) kg of vocs (ethanol) per year from fermenter venting

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. a)- true b)- false
