In one of the shops, there are some cylinders stored. Questions have been asked as to how they know the cylinders are safe, what happens if there is a change in temperature, etc. You decide you may need to brush up on your knowledge of high-pressure cylinders.

Perform the calculations identified below. Show your work neatly and clearly in a manner like the examples provided in Lesson 3 (i.e., write the formula, define each variable in the formula, show steps of your calculations, identify any conversion factors used).

After calculating each step, round the answer to the nearest tenth before proceeding to the next step's calculation.

A DOT 3AA-2265 high-pressure cylinder is used to store nitrogen (N2). The tank measures 7 inches (18 centimeters) in diameter and 43 inches (109 centimeters) high. Calculate the volume of the cylinder (in liters).

Formula: V = r2h

Complete the calculations for the volume, provide the answer to one decimal place, and include the unit of measurement (cm3). Blank 1 Complete the conversion of the cm3 to liters, provide the answer to one decimal place, and include the unit of measurement (L). Blank 2 What is the weight (in pounds) of the gas in the cylinder if it were filled with 185 moles of nitrogen? Provide the answer to one decimal place, and include the unit of measurement. Blank 3 Calculate the internal pressure (in psi) if the cylinder had been filled at 65 F. Formula: PV=nRT. Provide the answer to one decimal place, and include the unit of measurement. Blank 4 Do you have any concerns about having this cylinder in your facility or on your job site? (Yes or No) Blank 5 Why or why not? Blank 6 Recalculate the internal pressure (in psi) if the cylinder becomes heated to 110 F. Provide your answer to one decimal point, and include the unit of measurement (psi). Blank 7 What is the maximum number of moles of nitrogen that can be placed in the cylinder at this temperature and not exceed DOT regulations? Provide the answer (no decimal place), and include the unit of measurement (mol). Blank 8 What is the maximum weight (in pounds) of nitrogen that can be placed in the cylinder at this temperature and not exceed DOT regulations? Provide the answer to one decimal place, and include the unit of measurement (lb). Blank 9
