At what rate must heat be supplied to 15.0 kg/s of air, if the temperature is increased from 61.0°C to 650°C?

a) Calculate the rate that heat must be supplied by integrating the heat capacity formula for air.

b) Calculate the rate that heat must be supplied using the specific enthalpy table of gases located in your text by following the steps below. What is the specific enthalpy of air at 61.0°C, if the reference state is pref = 1 atm, and Tref = 25°C? Use the specific enthalpy table of gases in your text for this calculation.

c) What is the specific enthalpy of air at 650°C, if the reference state is pref = 1 atm, and Tref = 25°C. Use the specific enthalpy table of gases in your text for this calculation.

d) Calculate the rate that heat must be supplied to 15.0 kg/s or air.

Any values not given need to be looked up.

Tax on risk and capital. Some city-level officials argue that targeted tax breaks will be good for their city. Other officials argue that there should be a state law that bans the use of targeted state-level tax breaks.

Explain why both arguments are reasonable. Would it be reasonable for the same city-level official to make -or at least to believe in- both arguments simultaneously?

Effects of Fiscal Policy in the Long Run

Suppose that the government suggests cutting both taxes and government purchases by equal amounts. Use the classical model to illustrate graphically what happens to the real interest rate and national saving in response to this balanced-budget change. In addition, state and explain what the long-run effects of this policy would be on private saving (S^p), investment (I), real interest rate (r), and consumption (C).

An engineer wants to measure the bias in a pH meter. She uses the meter to measure the pH in 6 neutral substances and obtains pH readings of 7.08, 7.04, 7.07, 6.99, 7.10, and 7.12.

a.   Find the mean and standard deviation for the pH values (show your work).

b.   Create a 95% confidence interval for the pH values read by this meter. Use a t critical value of 2.571.

c.   Explain in context what your confidence interval tells you about the pH values read by this meter.

d.   The actual pH of the substances tested was 7. Is there evidence the pH meter is testing inaccurately?

You have a tax client who is a single taxpayer and has one child, age 3. Your client plans on sending to the child to private elementary, middle, and high school. He also plans on paying as much as he can for the child’s college education. Provide a paragraph explanation, directed to your client, advising him on information related to a Section 529 account. Use specific numerical examples in your explanation.
