The space between the panes of a double-glazed window can be filled with either air or carbon dioxide at atmos- pheric pressure. The window is 1.5 m high and the spac- ing between the panes can be varied. Develop an analysis to predict the convection heat transfer rate across the window as a function of pane spacing and determine, under otherwise identical conditions, whether air or car- bon dioxide will yield the smaller rate. Illustrate the results of your analysis for two surface-temperature conditions: winter (-10°C, 20°C) and summer (35°C, 25°C).
Consider a germanium wafer which has been doped with antimony to become extrinsically semiconducting at room temperature. What type of semiconductor is antimony doped germanium? What are the majority (or dominant) charge carriers in this material nea..
A single-row deep groove ball bearing operating at 1500 rpm is acted upon by a 2668 lb. radial load. The inner ring rotates, the load is steady and the service is continuous. Determine the rating life in hours if the basic load rating is 9210 lb.
The wearing parts of a coal mining machine are made of hardened tool steel, but are rarely, if ever, lubricated. The left and right wear plates for a typical tracked vehicle measure 48" long by 6" wide, and each tests at 360 HB. The vehicle weighs 10..

Air at 22 kPa, 220K and 250 m/s enters a turbojet engine in flight at an altitude of 10,000m. The diffusor slows the air down to a very low speed relative to its inlet. The pressure ratio across the compressor is 12. The turbine inlet temperature is ..

Choose the beam dimension a to reduce the deflection to below 1cm whilst minimising the mass of the beam.
a process occurs taking 5kg of mass from state a to state b. the work during this adiabatic process is 5kj. the change
A heat pump system is being designed to maintain a temperature of 25 0C when it is 0 0C outside. Assuming the heat transfer from the walls and roof is 4,000 MJ, determine the minimum theoretical net work input required if the cold reservoir was a) th..
Determine, the tensile stress in the component when first loaded, the temperature at which the stress will be zero if the component is rigidly held at its extended length.
