initial                                                               final

p1 = 760mmHg                                             p2 = 975mmHg

V1 = 4.9L                                                       V2 =

    P1V1    = P2V2

       V2   = P1V1/P2

               = 760*4.9/975   = 3.82L

Compute the Austin Brewery’s operating income when the denominator-level capacity is (a) theoretical capacity, (b) practical capacity, and (c) normal capacity utilization.
Alternative denominator-level capacity concepts effect on operating income. Lucky Lager has just purchased the Austin Brewery. The brewery is two years old and uses absorption costing. It will “sell” its product to Lucky Lager at $45 per barrel. Paul Brandon, Lucky Lager’s controller, obtains the following information about Austin Brewery’s capacity and budgeted fixed manufacturing costs for 2009: 1.         Compute the budgeted fixed manufacturing overhead rate per barrel for each of the denominator-level capacity concepts.

The terrace roof of a building at sea level is planned to have a rectangular floor area with dimensions of 10 m and 20 m. The prevailing wind speed in winter is u∞=25 km/h, and air temperature is assumed to be T∞=0°C. Considering that the outer surface temperature of the building is To=10°C, how should the building be positioned with respect to the prevailing wind direction to minimize the heat loss from the roof?
