5.75 A heating system must maintain the interior of a building at TH = 20 degree C when the outside temperature is T = 2 degree C. If the rate of heat transfer from the building through its walls and roof is 16.4 kW, determine the electrical power required, in kW, to heat the building using (a) electrical-resistance heating, (b) a heat pump whose coefficient of performance is 3.0, (c) a reversible heat pump operating between hot and cold reservoirs...

please read this articel and write one page summary atleast 250 words: MLB managers learn Spanish to unite teams and clubhouses: At spring training of 1962, the newly hired manager of the San Francisco Giants, Alvin Dark, gathered several of his side's Latin American players together behind second base. Once there, he gave an order that left them surprised, stunned and outraged. "He told us that we couldn't speak Spanish to each other in the clubhouse", said Orlando Cepeda, who...

In a vapor-compression refrigeration heat pump cycle with Refrigerant 134a as the working fluid provides heating at a rate of 15 kW to maintain a building at 20 °C year-round. During the heating mode in the winter, the outside temperature is 5 °C. It is also used for cooling in the summer when outside temperature is 34 °C. Saturated vapor at 2.4 bar leaves the evaporator and superheated vapor at 8 bar leaves the compressor. There is no significant heat...
