assuming a high value residential with 100 people in percentage and annual growth rate of 20% metered with uniform tariff . determine the maximum daily water demands after 5 years that includes fire with duration flow of 4min what will be the storage capacity in this residential area . assume no water losses

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
