Several different incandescent radiation sources are listed in the table below, along with their respective temperatures. Sunlight is provided as a baseline measurement at the top of the table. You will determine the peak intensity for each source with respect to its visible color spectrum. You also estimate the amount of emitted energy that falls in the visible light spectrum. To do so drag the slider to reach the temperature listed in the first column of the table. You can also type in the temperature value in the text box above the temperature slider. use the buttons to zoom in or out on either the vertical or horizontal axis to easily observe the curve (and the peak). The peak should be as high as possible, while still being visible on screen. You should extend the scale far enough to the right to see the curve reach very close to zero emission on the right. estimate the percentage of emitted energy that appears to fall within the visible spectrum and enter that value in the table. You can do this by estimating the area under the energy curve in the visible region as compared to the total area under the curve.

Orque can be calculated by multiplying the force (n) applied at 90? to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n? m. if the force (at 90? to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure. (3.32 mw; 9.69 mw; 4.25 mw; 5.82 mw)
