Around twenty rooms in the hotel are equipped with generators of around 5 kilowatts.
The hotel's electrical distribution equipment is directly proportional to the number of rooms. A 20-room hotel requires more energy than a single house, so the generator power required is also greater. The electricity consumption situation of a 20-room hotel will also be different. For example, when providing hot water, television, computers and other electrical equipment, factors such as the hotel's peak power consumption and backup power should also be considered . A common generator of around 5 kilowatts can meet the regular electricity needs of 20 hotel rooms.
A generator refers to a mechanical device that converts other forms of energy into electrical energy.
It also depends on the fall (height)water. Suppose the head is H (m), the flow rate is Q (m3/h), the power is P (kW) and the density of water is d (1000kg/ m3), the acceleration of gravity g = 10m/s2, taking into account the conversion efficiency μ, the relevant formula is: P = μdgHQ/3.6, if: μ=0.6, P=5kW, d= 1000kg/m3, H = 2m, Then Q = 3.6P/(μdgH) = 3.6x5/(0.6x1x10x2)= 1.5m3/h.
That is, when the generator has a height difference of 2 meters and a conversion efficiency of 0.6, the required water flow is about 1.5 meters cube per hour.
