Consider a continuous-flow, indraft supersonic wind tunnel, which uses a vacuum pump to draw atmospheric air from outside of the wind tunnel building through a converging-diverging nozzle, to establish the supersonic flow in the test section. Assuming a standard day in Morgantown, WV (elevation of 961 feet) and a Mach number of 2.0 in the test section, compute the following:_____
a) The test section temperature
b) The test section pressure, assuming isentropic flow
c) The test section velocity
d) The change in the specific enthalpy of the air

Bob would like to run his house off the grid, therefore he needs to find out how many solar panels and batteries he needs to buy.

The power output of a 250 W solar panel is p=250−10(t−5)2 watts for the average 10 hour day. He plans on using 12 V, 120 A⋅h batteries and would like to able to store 3 days worth of energy. Bob's house uses 1100 kW⋅h per month (30 days).

In your own words how does an airplane take off?

Please answer ASAP!!

How do we define energy efficiency?

А.) the ratio of the actual output energy to the input energy

B.) the ratio of power gain to power loss

C.) the product of input power and output power

D.) the sum of potential and kinetic energy

Consider one-dimensional heat conduction through a large plane wall with no heat generation that is perfectly insulated on one side and is subjected to convection and radiation on the other side. It is claimed that under steady conditions, the temperature in a plane wall must be uniform (the same everywhere). Is this claim reasonable
