At the moment gasoline costs $0.74/liter in the US,
and optimistic estimates of biobutanol costs are around
$1.3399999999999999/liter. For greenhouse gas emissions, we’ll need
to use lifecycle estimates that account for emissions at all stages
of production and use, since biofuels lead to emissions from cars
but involve negative emissions when plants used to make fuels
absorb CO2. Lifecycle estimates of gasoline are 3.3 kg
CO2e/liter; lifecycle estimates of biobutanol have
substantial uncertainty, but 1.7 kg CO2e/liter is a good
central estimate. As with most alcoholic biofuels, biobutanol is
less energy-dense than gasoline, 30 MJ/liter as opposed to
gasoline’s 35 MJ/liter.
Give the cost of mitigation in $/tCO2e.

According to The Economist (2019), it is difficult to be
optimistic about trade at the moment: almost the entirety of
US-China trade is covered by an average 25% tariff (up from an
average 5% at the start of 2018), Japan and Korea are putting up
trade barriers over a history spat, and the WTO's dispute
settlement mechanism looks set to become ineffective in December,
with the US blocking the required reappointment of judges. However,
unexpected developments are providing reasons for...

A vehicle burns gasoline (density = 0.79 kg/liter) at a rate of
7.6 liters per hour. Although gasoline is a mixture of many
chemicals, for simplicity assume it has the formula of octane,
C8H18.
What is the required air flow rate in molar units (kmol/hr),
in mass units (kg/hr) and in standard volume units (standard m3/hr)
for air fed in stoichiometric proportion?
Determine the flowrate (kmol/hr) and composition (mol
fraction) of the exhaust gases if 25% excess air...

The CDC estimates that 20% of people in the US between the ages
of 15 and 24 have an STI. Suppose we do a test at a local college
campus and find that 11 out of 117 people tested have an STI. Is
this random variation or does this school have a lower than average
level of infection?
What test should we perform and why?
What is your null and alternative hypothesis?
Perform the test. What is the test statistic...
