A pump operating at 1170 rpm discharges 2000 gpm at a total head of 109 feet. If the pump speed is increased to 1770 rpm, what is the brake horsepower (BHP, in kW) if the pump efficiency is 72% at the new pump speed? Water temperature is 70 °F. Round your answer to the nearest whole kilowatt. (Conversion factor: 1 horsepower = 745.7 W)

Your car tire is rotating at 3.4 rev/s when suddenly you press
down hard on the accelerator. After traveling 240 m, the tire's
rotation has increased to 6.6 rev/s. The radius of the tire is 32
cm.
What was the tire's angular acceleration? Give your answer in
rad/s^2.
Express the answer using two significant digits.
The answer I got is, approximately, 0.013405, but, apparently,
it's wrong.

At Kate's next appointment, Paula showed Kate how to use a
glucose meter. She instructed Kate to measure her blood glucose
level twice a day before and after breakfast and dinner. Paula
explains to Kate that her pre-meal blood glucose level should be
110 mg/dL or less, and if it increases by more than 50 mg/dL, she
needs to lower the amount of carbohydrates she consumes. Kate and
Paula proceed to plan several meals. Because a meal should contain
