- H2. Cartons of product are accumulated on the floor adjacent to a conveyor. The job consists of a worker lifting the cartons from the floor and placing them on the conveyor. The height of the conveyor is 61 cm. The cartons are 30 cm height, 30 cm width, and 40 cm length . The horizontal distance from the worker’s ankles to the center of the carton is 20 cm. Carton weight is 9 kg. Frequency of lift is 2 lifts per minute and the duration of the task is between 1 and 2 hours. The cartons have a fair handholds. Control at the destination of lift is not required. The angle of asymmetry at the origin of lift may be taken to be 45 degrees. Use the NIOSH equation to calculate the Recommended Weight Limit (RWL) and the Lifting Index (LI). Comment on the safety of this lifting task.A 25L bag was filled with air, a 10uL sample was then injected into the bag to make 50ppmv vapor sample. Can you explain how you get to the 50ppmv?Cereal is being dried in a vertical drier by air flowing countercurrent to the cereal. To prevent breakage of the cereal flakes, some of the exit air from the drier is recycled back to mix with the the moist fresh air. For each 1000 kg/hr of wet cereal fed to the drier, calculate the input of moist fresh air in kg/hr and recycle rate in kg/hr. The available data on stream compositions is (fractions): For water: Fresh air: 0.0132 Wet cereal: 0.200 Exit air: 0.263 Dried Cereal: 0.050 Air entering Dryer: 0.066

- To evaluate the use of renewable resources, an experiment was carried out with rice hulls. After pyrolysis, the product gas analyzed 6.4% CO2, 0.1% O2, 39% CO, 51.8% H2, 0.6% CH4, and 2.1% N2. It entered a combustion chamber at 90 °F and a pressure of 35.0 in. Hg and was burned with 40% excess air (dry) at 70 °F and an atmospheric pressure of 29.4 in. Hg; 10% of the CO remains. a. How many cubic feet of air were supplied per cubic foot of entering gas? b. How many cubic feet of product gas were produced per cubic foot of entering gas if the exit gas was at 29.4 in. Hg and 400 °F?A student is given a sample of a pink manganese (II) chloride hydrate. She weighs the sample in a dry, covered crucible and obtains a mass of 26.742g for the crucible, cover, and sample. Earlier she had found that the crucible and cover weighed 23.599g. She then heats the crucible to drive off the water of hydration, keeping the crucible at red heat for about 10 minutes with the cover slightly ajar. She then lets the crucible cool and finds it has a lower mass; the crucible, cover and contents then weigh 25.598g. In the process the sample was converted to off-white anhydrous MnCl2. a. What was the mass of the hydrate sample? _ghydrate b. What is the mass of the anhydrous MnCl2? _gMnCl2 c. How much water was driven off? _gH2O d. What is the percent by mass of water in the hydrate? water=massofwaterinsamplemassofhydrateinsample100 _massH2O e. How many grams of water would there be in 100.0g hydrate? How many moles? _gH2O; _molesH2O f. How many grams of MnCl2 are there in 100.0g hydrate? How many moles? What percentage of the hydrate is MnCl2? Convert the mass of MnCl2 to moles. The molar mass of MnCl2 is 125.85g/mol. _gMnCl2; _molesMnCl2 g. How many moles of water are present per mole MnCl2? _ h. What is the formula of the hydrate? _23 ft^3 of air was drawn from a ventilation duct and measured by means of a dry gas meter. the meter's temperature averaged 60 F and the meter gage pressure was -1.9" H2O. Barometric pressure during the sampling was 752 mm Hg. Calculate the volume in standard cubic feet and in standard cubic meter (25C, atm) this is an ideal gas problem
