A rectangular room has dimensions,
length 3.5m ; width 4.5m ; height 3.25m
A mercury barometer in the room shows a pressure equal to a height of column of mercury of 760mm and a thermometer in the room shows a temperature of 18oC.
Density of mercury = 13550 kg/m3 Gas constant for air, Rair = 287 J/kg K
Acceleration due to gravity = 9.807 m/s2
a) What is the air pressure in the room ? kPa
b) What is the temperature of the air in the room ? K
c) What is the density of the air in the room ? kg/m3
d) What is the mass of air in the room ? kg
Fireclay brick of dimensions 0.06 m x 0.09 m x 0.20 m is removed from a kiln at 1600 K and cooled in air at 40oC with h=50 W/m2/K. What is the temperature at the center and at the corners of the brick after 50 minutes of cooling?
Evaluate the maximum theoretical power that can be developed by the turbine, in kW, and the corresponding exit temperature.
Cantilever Beam with maximum tensile strength. A cantilever beam is to be made using a symmetrical I section beam. The cantilever is to carry a load of 40kN at a distance 2.5m from the fixed end. The situation allows for a depth of I beam to be no..
