In one of her experiments, she used a binary mixture of n-pentane (density 39.1 lbm/ft^3) and p-xylene (density 53.8 lbm/ft^3). One outlet stream of her condenser was measured to have a flow rate of 37 ft^3/min and a concentration of 30/70 n-pentane/p-xylene by volume. The other outlet stream was measured to have a flow rate of 22 ft^3/min and a concentration of 50/50 n-pentane/p-xylene by volume. If the system operates at steady state and the only inlet to her condenser has a flow rate of 59 ft^3/min, what is the inlet concentration of n-pentane in % by volume? Your answer should be between 0 and 100. Round your answer to 1 decimal place for entry into eCampus. Do not enter units. Example: 12.3

According to information found in an old hydraulies book, the energy loss per unit weight of fluid flowing through a nozzle connected to a hose can be estimated by the formulah = (0.04 to 0.09) (D/d) ^4*V^2/2*g where h is the energy loss per unit weight, D the hose diameter, d the nozzle tip diameter, V the fluid velocity in the hose, and g the acceleration of gravity. do you think this equation is a valid in any system units? Explain.

You get invited to a party at a 1,200 sf apartment, where there are a total of 23 people. The apartment has ceilings that are 8 ft above the floor. Three people begin smoking 2 cigarettes per hour each. The air handler system has a make-up air ventilation rate of 600 cfm. Assume an overhead fan ensures the air is well-mixed. Eye irritation from formaldehyde can start at concentrations of 0.01 ppm, with irritation of the lungs at 5 ppm. Will the concentrations become high enough to cause eye irritation

A piece of corroded metal alloy plate was found in a submerged ocean vessel. It was estimated that the original area of the plate was 800 cm2 and that approximately 7.6 kg had corroded away during the submersion. Assuming a corrosion penetration rate of 4 mm/yr for this alloy in seawater, estimate the time of submersion in years. The density of the alloy is 4.5 g/cm3.
