12) A heat engine operates between a source at 550°C and a sink at 25°C. If heat is supplied
tothe heat engine at a steady rate of 1200 kJ/min, determine the maximum power output
of this heat engine.
find the form factor and peak factor of the triangular wave shown in fig.11.38
an alternating voltage of 200 sin 471 t is applied to h.w rectifier which is in series with a resistance of 40 ohms. if the resistance of the rectifier is infinite in one direction and zero in the other. find the RMS value of the current drawn from the supply source
what is the peak value is sinusoidal alternating current of 4.78 rms amperes
a) Calculate the number of lamps required, the wattage of each lamp, and the proper
distribution of the lamps of your house. Your calculation will depend on-
- No of Rooms/Spaces in your house
- Name or Type of Rooms
- Area of Your Rooms/Spaces
- Maintenance Factor: 0.75 [Let]
- Utilization Factor: 0.5 [Let]
- Space to Height Ratio: Between 1 and 1.5 [Select based on your selected light or
assumption]
- Other information if needed (May take reference of BNBC 2020 or internet)
b) Calculate the illumination generated in each room/space by your existing lighting
setup of your house.
c) Compare results of (a) and (b). Comment on the results.

Analyze all loaded structures below using the consistent deformation method. Before commencing with the calculations, identify first the respective degree of indeterminacy.
Then draw the shear and moment diagram.
The width at upstream of the channel and width at the throat are 2.5m and 1.5m.
i) calculate flow rate in the channel using continuity and specific energy principles.
ii) calculate specific energy at constriction where z = 0.122
iii)if depth at the constriction is critical depth, determine new flow rate.
