65 kg of foodstuff containing 73% water will be dried to 8% moisture content at 85 ° C. In the process of drying at atmospheric pressure, if the first temperature of the food is 23 ° C, calculate the heat energy (kj) required for the drying process (the heat capacity of the food is 3.2 kj / kg ° C and the heat capacity of the water is 4.186kj / kg ° C).

A nuclear power station is situated in Coal Valley, which is a roughly rectangular valley that is 5 km long, 2 km wide, and 200 m deep. You have been asked to evaluate the effects of a worst-case scenario where the reactor housing fails, and radiation is released to the atmosphere. In your evaluation, you determine that 120 kg of Iodine-131 (a radioisotope that causes thyroid gland and liver damage) could be released into the atmosphere. Assuming the release of Iodine-131 was very rapid and all of it was uniformly distributed through the valley’s atmosphere with none escaping the valley, what would the concentration of Iodine-131 be in the valley’s air? Your answer should be expressed in units of ppm(v), and you may assume an atmospheric pressure of 1.0 atm and a temperature of 20oC. 2. Assuming the Iodine-131 concentration you calculated in part (a) is the initial concentration in the valley, you now want to determine the time it will take for the concentration to decrease to…
a) The number of kilocalories in food is determined by calorimetry techniques in which the food is burned and the amount of heat transfer is measured. How many kilocalories per gram are there in a 5.00-g peanut if the energy from burning it is transferred to 0.500 kg of water held in a 0.100-kg aluminum cup, causing a 54.9C temperature increase? (b) Compare your answer to labeling information found on a package of peanuts and comment on whether the values are consistent.
1. Residual oil, with a heating value of 18,480 BTU/bm, is used as a fuel in a power plant which produces 947,870 BTU/s of electricity. The overall efficiency of the power plant is 52 Determine the: a. Heat input, in BTUs b. Daily fuel consumption, in lbm C. Dimensions of the cylindrical storage (assuming length is equal to the diameter), in ft. d. Heat rejected the environment, in BTU/s. The density of the oil is 62 ID/ft.
Saponification is a process wherein soap is added to a certain type of oil to produce grease. One such grease is said to have 75.7 % by volume oil and 24.3% by volume soap, wherein the oil and soap have densities 760 kgm/m3 and 6,250 kgm/m3, respectively. This kind of grease is sold by packs shaped like a sphere with a diameter of 20 cm for convenience. Calculate: a) the mass of oil per pack (kgm), b) the mass of soap per pack (kgm), c) the weight of each pack (kgf), d) the specific weight of grease (N/m3), e) will the grease float if it is placed in water whose density is 1000 kgm/m3? Explain.

The artisanal production of cold-pressed extra virgin olive oil proceeds as follows. A stream of mixed ripe and unripe olives, around 3000 kg/d, are ground to a fine paste using large stone mills. The paste is then loaded into fiber disks, stacked together, and pressed to extract the liquid portion (oil and water) of the paste. What remains In the fiber disks is the pulp with a little amount of adhering llquid. The pulp is discarded, often used as an animal feed additive. The extracted liquid, which contains oil ar water, is then fed to a centrifuge to accelerate the separation of oil and water. Assuming perfect separation is achieved, pure olive oil and residual water can be separately obtained. The obtained olive oil can now be bottled and sold. Raw dives are composed of 21.44% oil, 52.83% water, and the remaining is solids. The pulp product of the pressing process contains 86.50% solids, and the balance is a mixture of oll and water which has the same ratio as the oil and water in…
A food product with 85% moisture content is being frozen. Estimate the specific heat of the product at -10°C when 80% of the water is in a frozen state. The specific heat of dry product solid is 2 kJ/(kg °C). Assume specific heat of water at -10°C is similar to specific heat of water at 0°C. And the heat of the types of ice follow the function of Cp ice = 0.0062 Tfrozen + 2.0649. Cp frozen product = ... kJ/kg °C.

The natural water content of a sample taken from a soil deposit was found to be 11.5%. It has been calculated that the maximum density for the soil will be obtained when the water content reaches 21.5%. Compute how much water must be added to 22,500 Ib of soil (in its natural state) in order to increase the water content to 21.5%. Assume that the degree of saturation in its natural state was 40% and G = 2.7.
After the sinking of RMS Titanic, US operated the International Ice patrol with the purpose of monitoring the presence and movements of icebergs in the Atlantic and Arctic oceans. Once, they observed a unique tabular iceberg in a form of a rectangle (250 km x 50 km x 300 m). How many years would it take to melt the iceberg solely by heat from the sun if the ice absorbs a mean of 98 J/m2 -s, 12.5 hrs per day? Note: the exposed area for heating is 250 km x 50 km and the density is 920 kg/m3 . This is my solution.
