Oxygen at 300 kPa and 90°C flowing at an average velocity of 3 m/s is expanded in an adiabatic nozzle. What is the maximum velocity of the oxygen at the outlet of this nozzle when the outlet pressure is 60 kPa? Use the table containing the ideal gas specific heats of various common gases.
The maximum velocity of the oxygen at the outlet of this nozzle is 532.5 Numeric ResponseEdit Unavailable. 532.5 incorrect.m/s.
A container filled with 70 kg of liquid water at 95°C is placed in a 90-m3 room that is initially at 12°C. Thermal equilibrium is established after a while as a result of heat transfer between the water and the air in the room. Assume the room is at the sea level, well sealed, and heavily insulated.
NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.
Determine the amount of heat transfer between the water and the air in the room.
The amount of heat transfer between the water and the air in the room is kJ.
A strain gauge rosette that is attached to the surface of a stressed component
gives 3 readings (ɛa = A, b = B, &c = C). If the strain gauge rosette is of the D°
type (indicating the angle between each of the gauges), construct a Mohr's Strain
Circle overleaf. You should assume that gauge A is aligned along the x-axis.
Using the Mohr's Strain Circle calculate the:
(i) principal strains (ε1, 2)?
(ii) principal angles (1, 2)?
You should measure these anticlockwise from the y-axis.
(iii) maximum shear strain in the plane (ymax)?
