Describe the energy storage technologies (8 marks) A hydropower storage system to provide 2GWe of dispatchable power for twelve hours is to be built between two reservoirs with a difference in elevation of one mile. Determine the minimum volume of water assuming a margin of safety of 50% and an average water depth of twenty feet in each reservoir. State all assumptions made. (4 marks)
Class activity 3 1- List at least 3 advantages of thermal energy storage 2- List at least 3 disadvantages of thermal energy storage 2. Explain clearly the principle of operation of the solar hot water system shown below
5. Sketch and describe a few Thermal Energy Storage (TES) technologies.
16-7 A magnetic energy-storage coil is constructed of a conductor of square cross section 40 x 40 cm, and a mean diameter of 32 m. Calculate the number of tus necessary for a stored energy of 5 MWh if the current is 160,000 A.
QUESTION Briefly describe the Input, Process, Storage and Output (IPSO) components for an information system that enables people to grocery store. Here is the most basic scenario of this experience from the shoppers perspective: assume the starting point is that you (as a shopper) are already in the store selecting your items. When completed you proceed to the self-checkout lane to process your items. Some are just cans and Describe the IPSO system that makes this self checkout experience possible....
