A 6 ohm load is connected to a 120volt source through a pair of 0.25 ohm conductors. Calculate (a) the load current and voltage, b) the voltage drop in h line wires.
Three resistors A, B, and C are connected in series to a 120 volt source. If RA is = 64 ohms and EB = 40volts, when the current is 0.5 amp, calculate the resistances RB and RC.
Find out about the wall construction (number and type of layers) of a sauna (treatment and/or relaxation room), thereby determining the heat transfer mode, the range of ambient conditions under which they operate, typical heat transfer coefficients on the inner and outer surfaces of the wall, and the heat generation rates inside. Determine the size and methodology of the heating and air-conditioning system that will be able to maintain the typical sauna conditions, for when 10 persons are inside the sauna at the same time.
Find out about the wall construction (number and type of layers) of an atmospheric diving-suit (ADS), the heat transfer mode, the range of ambient conditions under which they operate, typical heat transfer coefficients on the inner and outer surfaces of the wall, and the heat generation rates inside. Determine the size and methodology of the cooling and/or heating system that is applied to maintain the diver body temperature from extreme low temperature conditions (say 3 °C) at depths reaching 600 m below sea level.
