Chemical Engineering/Environmental Engineering 100 Assignment #1 1. Due: September 20, 2002 9:30 a.m. A rocket uses 110L of liquid oxygen as oxidizer in 43s. What is the consumption rate of liquid oxygen in ft3/h? How many cubic meters are there in a rod of uniform circular cross-section that is 1/2-inch in diameter by 1.75 ft long?
Diethyl ether is a volatile organic compound. The vapor pressure of diethyl ether is 401 mm Hg at 18°C and the Hvap = 26.0 kJ/mol. Calculate the vapor pressure of diethyl ether at 40°C.
