Fish can be turned into fish meal, and the fish meal can be used as animal feed to produce meat or used directly as food for human beings. The direct use of fish meal significantly increases the efficiency of the food chain. However, fish-protein concentrate, primarily for aesthetic reasons, is used mainly as a supplementary protein food. As such, it competes with soy and other oilseed proteins. In the processing of the fish, after the oil is extracted, the fish cake is dried in rotary drum dryers, finely ground, and packed. The resulting product contains 65% protein. In a given batch of fish cake that contains 80% water (the remainder is dry cake denoted by BDC for "bone dry cake"), 100 kg of water are removed, and it is found that the fish cake is then 40% water. Calculate the weight of the fish cake originally put into the dryer. Figure E4.6 is a diagram of the process.

5.7 The average Reynolds number for air passing in turbulent flow over a 2-m-long, flat plate is . Under these conditions, the average Nusselt number was found to be equal to 4150. Determine the average heat transfer coefficient for an oil having thermal properties similar to those in Appendix 2, Table 18, at at the same Reynolds number and flowing over the same plate.
A steam reservoir is covered by a rectangular plate (its length is 1 m and width 2 m). The steam temperature is 95o C, and it is in contact with the plate.

For bacteriological testing of water supplies and in medical clinics, samples must routinely be incubated for 24 h at 37°C. Peace Corps volunteer and MIT engineer Amy Smith invented a low-cost, low-maintenance incubator. The incubator consists of a foam-insulated box containing a waxy material that melts at 37.0°C interspersed among tubes, dishes, or bottles containing the test samples and growth medium (bacteria food). Outside the box, the waxy material is first melted by a stove or solar energy collector. Then the waxy material is put into the box to keep the test samples warm as the material solidifies. The heat of fusion of the phase-change material is 205 kJ/kg. Model the insulation as a panel with surface area 0.490 m2, thickness 4.50 cm, and conductivity 0.012 0 W/m ? °C. Assume the exterior temperature is 23.0°C for 12.0 h and 16.0°C for 12.0 h. (a) What mass of the waxy material is required to conduct the bacteriological test? (b) Explain why your calculation can be done…

Air at 100 Fahrenheit and 2 atm is being passed over a shallow bed of naphthalene spheres that are 0.5 inch in diameter at a superficial velocity (v0) of 5 fts^-1. The MW of naphthalene is 128.2 g mol^-1, and it’s diffusivity in air at these operating conditions is 0.033 cm^2s^-1. The porosity of the bed is 0.40, and the total surface area of the naphthalene particles is 86.3 ft^2 for each 1 ft^3 of packed bed.The viscosity of air under these conditions is 0.0184 cP and the density of air is 0.0023 g cm^-3. The equilibrium concentration of naphthalene in the air under these conditions is 0.006 mol L^-1. Assuming the concentration of the naphthalene in the air stream is negligible, estimate the initial evaporation rate of the naphthalene in pounds per second from 1 ft^3 of bed.
