A first-order, irreversible liquid-phase reaction is taking place in a CSTR and 60% conversion is obtained. What is the minimum number of CSTR of the same size needed to place downstream in series to achieve 90% of total conversion.
A three phase 3-wire 50Hz system with 𝐸𝑅𝑊 = 400∠10°V, supplies an unbalanced delta connected load as shown Figure Q1. Take 𝑅𝑊𝐵 phase sequence and use Millman’s theorem to determine the following:: 1.1 The line currents: 𝐼𝑅, 𝐼𝑊 𝑎𝑛𝑑 𝐼𝐵.
Two (2) kg of an ideal gas at 1atm and 300C is placed inside a piston cylinder assembly. Heat was then applied allowing the piston to expand at constant pressure. If the gas has Cp of 1.35kJ/kg-K and Cv of 1.09kJ/kg-K, determine the work done by the gas (kJ) as it is heated to a temperature of 1000C. Determine also the final volume of the gas after expansion (m3).
a mixture containing 800 kg of naoh,300 kg of al2o3 and 600kg of hf is heated to 950 °c and reacts to completion. what is the maximum masss of na3alf6 is formed ?
A one meter of annealed copper 2.5 cm in diameter is drawn until its resistance is 100 times the initial resistance, its diameter afterward is?
(a) Derive the formula for elastic potential energy, PEE, in terms of applied force F, stiffness
constant k, and extension ΔL of a wire. State any assumptions made.
(b) Figure 4.6a shows a F versus ΔL graph for a wire of length 2.0 m and diameter 1.2 mm.
(i) Determine the stiffness constant of the wire from the graph.
(ii) Determine the Young’s modulus for the material of the wire.
(iii)What is a practical advantage of knowing the Young’s modulus as compared with the
stiffness constant of the wire?
A Civil Engineer proceeded to do the stadia survey work to determine the topography of a certain area. The transit was set up at a point A, with the line of sight horizontal, took rod readings from the rods placed at B and C which is 200 m and 60 m from A respectively.
what is the total interior angle at point c of the following azimuth are given AzimS(A-B)=577 degrees AzimN(C-A)=597 degrees
