5.1 For the existing system, what is the electrical input power drawn for the four high-demand months (power of 100kW delivered to the air) and the eight low-demand months (power of 25kW delivered to the air)? Show your calculations and round off to 1 decimal place.ods require the fan to deliver 100kW to the air and the lower flow rate periods require 25kW to be delivered to the air. Figure 3: Approximated power duration diagram (power transferred from the fan to the air). At present, these two different demands are handled by a single fan that is powered by a
