Refrigerant-134a is throttled from the saturated liquid state at 800 kPa to a pressure of 140 kPa. Determine the temperature dro
zavuch27 [327]

Answer:

The temperature drop is 61.1 °C

The final specific volume of the refrigerant is 1.236 m^3/kg

Explanation:

Initial pressure of refrigerant = 800 kPa = 800/100 = 8 bar

Final pressure of refrigerant = 140 kPa = 140/100 = 1.4 bar

From steam table

At 8 bar, initial saturated temperature is 170.4 °C

At 1.4 bar, final saturated temperature is 109.3 °C

Temperature drop = initial saturated temperature - final saturated temperature = 170.4 - 109.3 = 61.1 °C

Also, from steam table

At 1.4 bar, specific volume is 1.236 m^3/kg

Final specific volume of the refrigerant is 1.236 m^3/kg

Three groups of students are given study outlines for 6 weeks. One group studies 2 hours a night, a second group studies 1 hour
katrin2010 [14]

Answer:

The constant here is the study outline

Explanation:

In scientific research, the constant variable is that part/variable of the experiment that does not change or is set not to change. Examples include temperature, environment or height.

Assuming the scenery described in this question is an experiment. All the groups presented are bound by a constant during the experiment. The constant here is the study outline. The study outline provided to the students is not going to change.

NOTE: There could be confusion as regards the answer being the final exam grade but that will be the dependent variable as that will be the outcome of the experiment while the time spent to study will be the independent variable.
