A plane wall of thickness 0.1 m and thermal conductivity of 25 W/mL.
The volumetric heat generation of the wall = 0.3 MW/m^3.
The wall is well insulated on one side while the other side is exposed to a fluid at 92 degrees Celsius with a convection heat transfer coefficient of h=500 W/m^2.
What is the maximum temperature in the wall?
The U.S. Environmental Protection Agency (EPA) recommends that 222Rn levels not exceed 4 pCi per liter of air (1Ci=3.7x10^10 decay events per second; 1 pCi =1x10^-12 Ci).
If 1000 tons/day of wet sugar is fed to the evaporator, how much additional water must be removed from the outlet sugar to dry it completely, and what annual revenue can be expected if dry sugar sells for $0.15/lbm?

A paint mixture containing 25% of pigment and the balance water sells for $18.00/kg, and a mixture containing 12.0% pigment sells for $10.00 kg. If a paint retailer produces a blend in containing 17.0% pigment, for how much ($/kg) should it be sold t..
The line is commercial steel pipe, 25 mm internal diameter, length 120 m. The properties of the fluid are: viscosity 0.99 mNm-2 s, density 998 kg/m3. Calculate the total pressure drop due to friction when the flow rate is 3500 kg/h
Compute the increase in temperature and entropy if saturated liquid water at 10 kPa is pumped to a pressure of 9.0 MPa, if the pump is 75% efficient (where 100% efficiency would be reversible). You may use constant values and at these conditions.
Her model indicated that if Stogy hired two rollers per week during the entire first year, inventory would stand at 2,697,000 cigars by year's end.
