Mass of one component in two component w/feed flowrate

AI Thread Summary
The discussion focuses on calculating the mass of Triethylene Glycol from a feed flow rate of 70,000 gallons per day with a weight percent of 35%. The initial calculation attempted to convert gallons to milliliters but contained significant unit conversion errors. The importance of correctly converting units and maintaining proper dimensional analysis is emphasized, particularly the need to account for time in the final answer. The user acknowledges the mistake in unit conversion and plans to correct it for a lab report comparison. Accurate unit conversions are crucial for obtaining valid results in chemical calculations.

Homework Statement


Basically I'm given a feed flowrate - 70,000 gal/day
I know the weight percent is 35% and the component is Triethylene Glycol - density - 1.255g/ml

Homework Equations

The Attempt at a Solution


So i did this

70,000 gal/day * .35 * (.0378mL/1gal)* 1.255g/mL = g of Triethylene Glycol

Is this correct, i know the gal->mL might be wrong but is the basic setup correct using wt%?

You soft of have the right idea. But, "gal->mL might be wrong" is a gross understatement. Do you really think that 1/30 of a ml is the same as one gallon (1 gallon is close to 4 liters)? And the units of your answer are incorrect. What happened to "day."

Thanks! yeah, i knew it wasnt right the gal->mL i was just short on time and yeah i left off days, because i was going to convert it later to hours since I am comparing it to some charts for a lab report
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
