Praxis Physical Science - General Exam Info Sample Questions

A coal-fired electric power plant burns coal at a rate of 100 tons per hour.  The rate of air flow into the combustion chamber is 1.3 million pounds per hour. The useful energy output from that plant is 37% of the input energy.  What must the mass rate of flue gases being exhausted from the plant be if the rate of ash production is 10 tons per hour?





Correct Answer:
1.48 million pounds per hour.
to determine the mass rate of flue gases being exhausted from the coal-fired power plant, we need to apply the principle of conservation of mass. this principle states that the total mass entering a system must equal the total mass exiting the system when the system is at a steady state. we can use this principle to set up an equation accounting for all inputs and outputs of the system.

let's break down the inputs and outputs: 1. **inputs**: - coal is being burned at a rate of 100 tons per hour. since 1 ton is equal to 2000 pounds, the coal input can be calculated as \(100 \times 2000 = 200,000\) pounds per hour. - air is flowing into the combustion chamber at a rate of 1.3 million pounds per hour. 2. **outputs**: - ash is produced at a rate of 10 tons per hour, which equals \(10 \times 2000 = 20,000\) pounds per hour. - flue gases, which are the main subject of our calculation.

applying the conservation of mass, we set up the following equation: \[ \text{total input} = \text{total output} \] \[ \text{coal input} + \text{air input} = \text{flue gas output} + \text{ash output} \]

plugging in the known values: \[ 200,000 \, \text{lb/hr (coal)} + 1,300,000 \, \text{lb/hr (air)} = \text{flue gas output} + 20,000 \, \text{lb/hr (ash)} \]

to find the flue gas output, rearrange the equation: \[ \text{flue gas output} = 200,000 + 1,300,000 - 20,000 \] \[ \text{flue gas output} = 1,480,000 \, \text{lb/hr} \]

therefore, the mass rate of flue gases being exhausted from the plant is 1.48 million pounds per hour. this calculation ensures that the mass balance is maintained as required by the principle of conservation of mass, thereby confirming that the inputs and outputs within the system are equal.

Using a t-test or ANOVA are examples of using which statistical method?





Correct Answer:
comparative statistics


the correct answer to the question of which statistical method involves the use of a t-test or anova is "comparative statistics." this category of statistics is focused on comparing differences between groups or sets of data to determine if those differences are statistically significant.

comparative statistics includes various statistical tests and methodologies designed to compare data across different groups. two of the most common tools in this category are the t-test and anova (analysis of variance).

the t-test is generally used when comparing the means of two groups. it helps determine if the observed differences between these groups are significant or if they occurred by chance. there are different types of t-tests, including the independent samples t-test and the paired sample t-test, each serving specific experimental needs.

anova, on the other hand, extends the capabilities of the t-test to more than two groups. it is used to analyze the differences among group means and their associated procedures. the essence of anova is that it breaks down the variability in data into variability between groups and variability within groups. this helps in assessing whether the means of several groups are all equal or not.

therefore, when tasked with comparing two or more sets of data, particularly concerning their means, comparative statistics through tools like t-tests and anova is the appropriate approach. these statistical methods help in making informed decisions about the data, based on whether observed differences are statistically significant.
