Given data:
a= 10 cm.
L= 10 cm.
b= 20 cm.
H=40cm.
⚫ a = 10, cm: This could represent the width of the duct.
⚫b=20, cm: This might be the height of the duct.
⚫L = 10, cm: This usually stands for the length of the duct in
the direction of flow.
⚫H=40, cm: This could indicate the height of some
component or another duct-related dimension, but the exact
meaning depends on the experiment's context.
please explain each step and include drawings on the phase diagram. thanks

The exhaust (product) leaves the engine at 800 K, and the heat lost to the coolant is 3.4×105 kJ/kmol. What is the engine's output power? Assume both air and fuel (methane) inlet to the engine at 298 K. Take for methane, the molecular weight is M = 16 kg/kmol, and the heat of combustion is 50.01 MJ/kg.

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.arrow_forwardA 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)?arrow_forward
