- Discuss the modes of heat transfer that determine the equilibrium temperature of the space shuttle Endeavour when it is in orbit. What happens when it reenters the earths atmosphere?A manufacturer in the United States wants to sell a refrigeration system to a customer in Germany. The standard measure of refrigeration capacity used in the United States is the ton (T); a 1 T capacity means that the unit is capable of making about 1 T of ice per day or has a heat removal rate of 12,00 Btu/h. The capacity of the American system is to be guaranteed at 3 T. What is this guarantee in SI units?Subject: Thermodynamics What is the increase of temperature in degree F of 2 liters of water at 30°C after 1500 calories of heat have been added to?

Energy consumption in a country from 2001 to 2011 increased from 1041.3 million to 1526.1 million BOE (barrels of oil equivalent). If the high calorific value (HHV) of the oil is 141,000 kJ/gallon what is the increase in energy consumption over 10 years in Joule units. What is the rate of energy consumption per year? 2. Based on data on the rate of energy consumption per year from question no. 1, if the growth rate energy 2.5% per year, calculate the doubling time (td) and what is the approximate rate of energy growth in 2021.the specific heat (cp or cv) can also be understood as a "capacity or ability of a given material to store "heat". In this way, we can say that: 1- the greater the specific heat, the greater the amount of "heat" needed to cause an increase or decrease in temperature per unit mass of the material.2- the higher the specific heat, the lower the amount of "heat" needed to cause an increase or decrease in temperature per unit mass of the material3- the lower the specific heat, the greater the amount of "heat" needed to cause an increase or decrease in temperature per unit mass of the material4- the lower the specific heat, the amount of "heat" needed to cause an increase or decrease in temperature per unit mass of the material does not change5-the higher the specific heat, the amount of "heat" needed to cause an increase or decrease in temperature per unit mass of the material does not change choose only one of the above alternatives as correct

PLEASE WRITE THE COMPLETE SOLUTIONS/DIAGRAMS LEGIBLY. NO LONG EXPLANATION NEEDED. USE 3 DECIMAL PLACES. BOX THE FINAL ANSWER. An airplane is cruising at an elevation of 35,000 feet from sea level. Determine the amount of gage pressure in bars needed to pressurize the airplane to simulate sea level conditions. The average atmospheric pressure on earth is mated as a function of altitude by the relation Patm = 101.325 (1- 0.02256z)5.256, where Patm is the atmospheric pressure in kPa and z is the altitude in km with z = 0 at sea level.
