Explanation Write the formula to calculate coefficient of performance of reversible refrigerator ( COP R,rev ) . COP R,rev = 1 ( T H T L − 1 ) (I) Here, absolute temperature of high and low temperature reservoir is T H and T L respectively. Write the formula to calculate coefficient of performance of a refrigerator ( COP R ) . COP R = Q ˙ L W ˙ net,in (II) Here, amount of heat rejected rate from refrigerator is Q ˙ L and required power input to reversible refrigerator is W ˙ net,in Conclusion: Convert the unit of temperature T L from ° F to R . T L = 72 ° F = ( 72 + 460 ) R = 532 R Convert the unit of temperature T H from ° F to R . T H = 90 ° F = ( 90 + 460 ) R = 550 R Substitute 532 R for T L and 550 R for T H in Equation (I)

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a bur…

An office building is planned with a lateral-force-resisting system designed for earthquake resistance in aseismic zone. The seismic capacity of the proposed system, expressed as a force factor, is assumed tofollow a lognormal distribution with a median of 6.5 and a standard deviation of 1.5. The ground motionfrom the largest expected earthquake at the site is estimated to correspond to an equivalent force factor of 5.5.(a) What is the estimated probability that the building will experience damage when subjected to the largest expected earthquake? (b) If the building survives (i.e., experiences no damage) during a previous moderate earthquake with aforce factor of 4.0, what is the updated probability of failure of the building under the largest expectedearthquake?(c) Suppose future occurrences of the largest expected earthquake follow a Poisson process with a mean return period of 500 years. Assuming that damage events from different earthquakes are statisticallyindependent,…

During a plant visit, it was noticed that a 12-m-long section of a 10-cm-diameter steam pipe is completely exposed to the ambient air. The temperature measurements indicate that the average temperature of the outer surface of the steam pipe is 75°C when the ambient temperature is 5°C. There are also light winds in the area at 10 km/h. The emissivity of the outer surface of the pipe is 0.8, and the average temperature of the surfaces surrounding the pipe, including the sky, is estimated to be 0°C. Determine the amount of heat lost from the steam during a 10-h-long work day. Steam is supplied by a gas-fired steam generator that has an efficiency of 80 percent, and the plant pays $1.05/therm of natural gas. If the pipe is insulated and 90 percent of the heat loss is saved, determine the amount of money this facility will save a year as a result of insulating the steam pipes. Assume the plant operates every day of the year for 10 h. State your assumptions.

An old fashioned ice cream kit consists of two concentric cylinders of radii Ra and Rb. The inner cylinder is filled with milk and ice cream ingredients while the space between the two cylinders is filled with an ice-brine mixture. Ice cream begins to form on the inner surface of the inner cylinder. To expedite the process, would you recommend rotating the inner cylinder? Justify your recommendation. icecream/ ice-brine Ra Rb
