The turbines in a hydroelectric plant are
fed by water falling from a 40 m height.
Assuming 90% efficiency for
conversion of potential to electrical
energy, and 6% loss of the resulting
power in transmission, what is the
mass flow rate of water (in kg/min)
required to power a 150 W light bulb?

- A given soil sample is subjected for proximate analysis - specifically moisture content and analysis of inorganic matter (or ash) content. A cleaned and tared crucible is weighed in an analytical balance and found to be 4.5015 grams . The soil sample is weighed-in and the crucible, together with the plant sample, measured a total of 6.2525 grams. The set-up is then placed in an oven and dried to 105 degrees Celsius for at least two hours. The setup is cooled to room temperature in a dessicator and then measured to a constant weight of 5.9775 grams. Afterwards, the setup is placed inside the muffle furnace and ignited to 720 degrees Celsius for at least an hour. The set-up is cooled to room temperature again inside the dessicator and then measured to the constant weight of 4.9375 grams. (A) What is the percent moisture in the plant sample?

It is derived from the "fruit" of corn using a bioprocess that degrades corn starch into its constituent sugars. Given the quantity of corn syrup (d = 1.4 kg L^-1) needed for many industries. It should be no surprise that this product is often transported from place to place in tank cars (via railway) where the typical transport mass is 2.290 x 10^5lbs. In the space provided below, calculated the diameter in (meters) of such a tank car's 11.12m long-cylindrical transport container.

- 1) One of Dr. G’s CHEM 102 students is working part-time at a hardware store. A customer tells this student “I need a single stud (a wooden beam) from which I can cut two (2) pieces of 2.7m studs”. The student does the math, goes behind counter, and brings a stud cut to 5m length. Select the most sensible and scientific answer to this situation. A) 2.7 × 2 when operated as a significant figure multiplication, gets you 5 and the student is right. B) Hardware stores don’t comply with correct sig. fig. rules for measurements. C) The customer must pay for 5.4m worth; but he/she should only get 5m to take home. D) The word ‘Two (2)’ mentioned here carries infinite significance, so the student is wrong. E) The word ‘Two (2)’ mentioned here is not a ‘measurement’, therefore this is an example of a situation where there is disagreement between science and day-to-day life.arrow_forward1.
