If you put a straw into a glass of water, the straw looks bent, although nothing has really happened to the straw. The term that describes this property of light is

In a given rocket engine, a mass flow of propellants equal to 87.6 lbm/s is pumped into the combustion chamber, where the stagnation temperature after combustion is 6000°R.

In a steady-flow industrial process, m kg/s of an ideal gas flows through a heater at a constant mass flow rate. It is your job to select a heater that is powerful enough to heat the gas from T i (300 K) to T e (350 K).

The major resisting force in gravity dam?

Water is the working fluid in an ideal Rankine cycle. The pressure and temperature at the turbine inlet are 1200 lbf / in^2 and 1100°F, respectively, and the condenser pressure is 140 lbf/in^2 The mass flow rate of steam entering the turbine is 1.

Where might you find recommendation engines at work?

A completely reversible heat pump produces heat at a rate of 100 kW to warm a house maintained at 25℃. The exterior air, which is at 0℃, serves as the source.

A closed system undergoes a process in which work is done on the system and the heat transfer Q occurs only at temperature Tb. For each case, determine whether the entropy change of the system is positive, negative, zero, or indeterminate.
