Concept explainers

Conduction and Convection

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 burner, heats up because of the flame underneath it.

Question

One can change the system energy by work (W) and by heat transfer (Q). In a closed system, this is described by the following relation:
AE = Q - W
Enter the SI units (abbreviated as expected, for example, m instead of meter) for Q and W in the following format: X, X

The drag on an airplane wing in flight is known to be a function of the density of air (), the viscosity of air(), the free-stream velocity (U), a characteristic dimension of the wing (s), and the shear stress on the surface of the wing (s). Show that the dimensionless drag, sU2, can be expressed as a function of the Reynolds number, Us.
The gravitational constant g is 9.807 m/s2 at sea level, but it decreases as you go up in elevation. A useful equation for this decrease in g is g = a – bz, where z is the elevation above sea level, a = 9.807 m/s2, and b = 3.32 × 10–6 1/s2. An astronaut “weighs” 80.0 kg at sea level. [Technically this means that his/her mass is 80.0 kg.] Calculate this person’s weight in N while floating around in the International Space Station (z = 354 km). If the Space Station were to suddenly stop in its orbit, what gravitational acceleration would the astronaut feel immediately after the satellite stopped moving? In light of your answer, explain why astronauts on the Space Station feel “weightless.”

In the United States, electricity is sold using the SI units of kilowatt (kW) or megawatt (MW), and fuel for power generation stations is generally purchased using English units, e.g., British thermal unit (Btu), gallon (gal), and ton. An industrial power plant has an average annual load of 100 MW (electrical). If the overall thermal efficiency is 33% (based on HHV), what is the annual cost of fuel if the plant is fired with (a) natural gas, (b) No. 2 fuel oil, and (c) bituminous coal? Use the data from Tables 2.2, 2.7, and 2.13. Assume the cost of natural gas is $5/million Btu, the cost of No. 2 fuel oil is $3/gal, and the cost of bituminous coal is $60/ton (1 ton = 2000 lbm)

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
