Determine the pinch temperature and the minimum utility requirements for the process set out below. Take the minimum approach temperature as 15 °C. Devise a heat-exchanger network to achieve maximum energy recovery.
Fresh rainwater or surface water contains enough tritium ( ) to show 5.5 decay events per minute per 100. g of water. Tritium has a half-life of 12.3 years. You are asked to check a vintage wine that is claimed to have been produced in 1946.
Derive an equation for the latent heat of fusion that is a function of the radius of the particle. Using this equation, for a copper particle that has a radius of 2.5 nm, find the ratio of the latent heat of fusion of the particle to the laten..
Preliminary design work has been done on a process to recover a valuable product froman effluent gas stream. The gas will be scrubbed with a solvent in a packed column;the recovered product and solvent separated by distillation; and the solvent co..
Cite the indices of the direction that results from the intersection of each of the following pair of planes within a cubic crystal:
A condenser is required to condense n-propanol vapour leaving the top of adistillation column. The n-propanol is essentially pure, and is a saturated vapourat a pressure of 2.1 bara. The condensate needs to be sub-cooled to 45ŽC.Design a horizonta..
The biot modulus for a 3 cm diameter sphere at 100degree C subjected to a convective air flow resulting in an average convective heat transfer coefficient from the surface of 30W/m2
Zirconium is one of the few metals that retains its structural integrity upon exposure to radiation. The fuel rods in most nuclear reactors therefore are often made of zirconium.
High-density polyethylene may be chlorinated by inducing the random substitution of chlorine atoms for hydrogen.
A 1 m^3 isolated chamber with rigid walls is divided into two compartments of equal volume. The partition permits transfer of heat. One side contains a nonideal gas at 5 MPa and 300 K and the other side contains a perfect vacuum. The partition is rup..
Calculate the grams of H2O that will form on decomposition of 0.10 mole of ammonium nitrate
Latest commercial technologies, R&D in visbreaking with potential areas still need for improvement
-12 the gravimetric composition and properties of two different typical fuels i.e. coal and fuel oil is tabulated below- Parameters coal fuel oil Composition weight% -- C 76 85 H 4.5 11.5 S 0.5 3.5 N 1.0 -- O 3.0
