A tanker carrying toluene is unloaded, using the ship's pumps, to an onshore storage tank. The pipeline is 225 mm internal diameter and 900 m long. Miscellaneous losses due to fittings, valves, etc., amount to 600 equivalent pipe diameters. The maximum liquid level in the storage tank is 30 m above the lowest level in the ship's tanks. The ship's tanks are nitrogen blanketed and maintained at a pressure of 1.05 bar. The storage tank has a floating roof, which exerts a pressure of 1.1 bar on the liquid.
The ship must unload 1000 metric tons within 5 hours to avoid demurrage charges. Estimate the power required by the pump. Take the pump efficiency as 70%. Physical properties of toluene: density 874 kg/m3, viscosity 0.62 mNm-2 s.
Calculate the tower diameter and packing height and calculate NTU - Ammonia in air being absorbed by a pure water stream in a packed tower.
Derive a Differential Equation which will show how temperature in the tank changes with time. State assumption used. Solve this model to obtain T(t) given that T(t=200s) = 50°C.
A gas stream is entering a separator at 1 mole/sec with mole fractions 15% A and 85% B. (Component 1 is A, component 2 is B.) At surface, the gas stream is 8 bar and 350K. Two streams exit the separator, one primarily of A (0.99 A1, 0.01 A2), and one..
Calculate the molarity of each of these solutions. a. A 5.623-g sample of NaHCO3 is dissolved in enough water to make 250.0 mL of solution. b. A 184.6-mg sample of K2Cr2O7 is dissolved in enough water to make 500.0 mL of solution.
Calculate the equilibrium conversion, then redo parts (a) through (c) to achieve a concentration that is 90% of the calculated equilibrium conversion.
Using the steam tables estimate cp in (kj/kg k) , for super heated steam and 0.1 Mpas and 700deg c
The product is neutralized and washed with water to remove salts. The washed product is usually separated by batch distillation, in which unreacted feeds are recovered first, followed by product, and a polymeric waste is left as residue. The batch..

Write a function called int_col that has one input argument, a positive integer n that is greater than 1,and one output argument v that is a column vector of length n containing all the positive integers smaller than or equal to n, arranged in suc..
Develop the designed circuit using breadboard in the laboratory. Available thermal sensor can be used in the circuit. Discuss the effect of resistors on calibration of the sensor with specific emphasis on the sensitivity of the instrument.
What are some of the obvious and less obvious ethical issues involved in product recalls? How might these ethical issues come into conflict with a particular company's economic concerns?
