A marker is a pen with a thick tip made of felt, which is used for drawing and for coloring things.
Answer:
Flow velocity
50.48m/s
Pressure change at probe tip
1236.06Pa
Explanation:
Question is incomplete
The air velocity in the duct of a heating system is to be measured by a Pitot-static probe inserted into the duct parallel to the flow. If the differential height between the water columns connected to the two outlets of the probe is 0.126m, determine (a) the flow velocity and (b) the pressure rise at the tip of the probe. The air temperature and pressure in the duct are 352k and 98 kPa, respectively
solution
In this question, we are asked to calculate the flow velocity and the pressure rise at the tip of probe

Answer:
False
Explanation:
According to the AISI (SAE) statements the last two numbers of the designation indicates the porcentage of carbon in the steel. And the firs numbers indicate the most important alloy alements.
In the case of the AISI 1045 indicates that the composition of this steel is 0,45% of carbon.
Answer:
Recall the Entropy Balance (Second Law of Thermodynamics) equations for the system below
And for ideal gas, we know that
Change in Entropy of the air kJ/Kg.K, ΔS = S₁ - S
₂ = Cp Ln (T₂/T₁) - R Ln(P₂/P₁)
where R is gas constant =0.287kJ/kg.K and given
Cp=1.015 kJ/ kg.K
T₂ = 465k T₁=270k, P1=58kPa, P2=350kPa
substituting these values into the eqn above, we have
S = (1.015x 0.544) - (0.287x1.798)
S = 0.0363kJ/Kg.K
Hence, the mass specific entropy change associated with the compression process = 0.0363kJ/Kg.K
Random integer values can be generated with the randint() function. This function takes two arguments: the start and the end of the range for the generated integer values. Random integers are generated within and including the start and end of range values, specifically in the interval [start, end].
