Answer:
a)P-v
Explanation:
Isobaric:
Isobaric process is a process in which initial and final pressure will be same.This is also called constant pressure process.
If we take a process in which pressure is constant then there will be two possibility maybe this is compression process or maybe this is expansion pressure depending on the given condition.
In general only in P-v diagram ,isobaric processes are represented by straight lines.
If we take a saturated steam ,in which on T-s diagram pressure lines are represented by straight lines.
If we take the ideal gas Pv= mRT if we fix pressure then T-v digram will be linear diagram so we can say that here is also isobaric processes are represented by straight lines.
But from above most appropriate answer will be a.
Answer:
For a free stream velocity of 135 mi/hr compressibility effects begins in flow.
Explanation:
Calculate the maximum velocity using the following relation
Now substitute for and 270 mi/h for
⇒
135 mi/hr
Answer: c.An accumulator is not used in a system with a receiver/dryer
Explanation:
In a refrigeration system, a condenser is used to transfer heat and this occurs from the refrigerant to the air or water.
Then, the refrigerant then condenses to liquid when the hear has been transferred.
We should note that the condenser is normally mounted in front of the radiator. The receiver/dryer is a storage tank for the liquid refrigerant from the condenser.
The statement that an accumulator is not used in a system with a receiver/dryer is not true. This is because, the accumulator gives protection to the compressor which helps to prevent the failure of the compressor.
Therefore, the answer is C.
Answer:
get in a car accident and get hurt and you will have to be hospitalized and a lot more
Answer:
a) , b) , c) 1600
Explanation:
a) The Reynolds Number is modelled after the following formula:
Where:
- Fluid density.
- Dynamics viscosity.
- Diameter of the tube.
- Fluid speed.
The formula can be expanded as follows:
b) The Reynolds Number has this alternative form:
c) Since the diameter is the same than original tube, the Reynolds number is 1600.
