Answer:While structured analysis sees procedures and information as isolated segments, object-oriented (O-O) analysis joins information and the procedures that follow up on the information into things called objects. O-O analysis utilizes protest models to show information, conduct, and by what implies objects influence different articles. By portraying the items (information) and techniques (forms) expected to help a business task, a framework engineer can outline reusable segments for quicker framework usage and diminished advancement cost.Numerous experts trust that, contrasted and organized examination, O-O strategies are more adaptable, effective, and reasonable in the present unique business environment. Agile improvement techniques have pulled in a wide after and a whole network of clients.
Agile strategies ordinarily utilize a winding model, which speaks to a progression of cycles, or revisions,which depend on client criticism. Advocates of the winding model trust that this approach lessens dangers and accelerates programming advancement. Investigators ought to perceive that lithe techniques have points of interest and hindrances. By their tendency, dexterous strategies enable designers to be considerably more adaptable and responsive, however can be less secure than more customary techniques.For instance, without a point by point set of framework necessities, certain highlights asked for by a few clients won't not be predictable with the organization's bigger course of action. Other potential disservices of versatile strategies can incorporate feeble documentation, obscured lines of responsibility, and too little accentuation on the bigger business picture. Additionally, except if legitimately executed, a long arrangement of emphases may really add to extend cost and advancement time.
Answer:
The absolute air pressure, on top of reservoir is 3858.84 kPa
Explanation:
Given
Since
Also,
, hence
KL = 0.5 + 2 +0.2 = 2.7
Pressure loss of pipe =
f from Moody chart at μ = 1.307 × 10⁻³ kg/m·s and
Roughness ε = 0.00026 m whereby, relative roughness is ε/d = (0.00026 m)/ 0.02 m = 0.013
f= 0.042 and
Q = v·A = 1.5 L/s = 0.0015 m³/s
v = Q/A where A = π·(0.02²)/4 = 3.1416×10⁻⁴ m²
v = (0.0015 m³/s)÷(3.1416×10⁻⁴ m²) =4.775 m/s
Pressure loss of pipe, = 3733071.965 Pa
= 3858839.04 Pa
The absolute air pressure, on top of reservoir = 3858.84 kPa
Answer:
Both technicians are correct.
Explanation:
a. The rate of combustion of diesel as a fuel by diesel engines is lower compared to a gasoline engine. So if the two types of engine are operated with the same litre of fuel and for the same period, the gasoline engine would consume more fuel. Thus, a diesel engine would consume less fuel per mile than a gasoline engine.
b. Diesel engines are more powerful engine compared to a gasoline engine. They are used where a great amount of force is required. So that compared to a gasoline engine of the same size, a diesel engine would provide more torque.
Therefore, the two technicians are correct as regards their statements.
Answer:
d/dt[mCp(Ts-Ti)] = FCp(Ts-Ti) - FoCp(Ts-Ti) + uA(Ts-Ti)
Explanation:
Differential balance equation on the tank is given as;
<h3>Accumulation = energy of inlet steam - energy of outlet steam+ </h3><h3> heat transfer from the steam</h3><h3>where; </h3>
Accumulation = d/dt[mcp(Ts-Ti)]
Energy of inlet steam = FCp(Ts-Ti)
Energy of outlet steam = FoCp(Ts-Ti)
Heat transfer from the steam = uA(Ts-Ti)
Substituting into the formula, we have;
<h3>Accumulation = energy of inlet steam - energy of outlet steam+ </h3><h3> heat transfer from the steam</h3><h3 /><h3>d/dt[mCp(Ts-Ti)] = FCp(Ts-Ti) - FoCp(Ts-Ti) + uA(Ts-Ti)</h3><h3 /><h3 />
