thermal energy is being added to steam at 475.8 kPa and 75% quality. determine the amount of thermal energy to be added to creat
eduard

Answer:

q_{in} = 528.6\,\frac{kJ}{kg}

Explanation:

Let assume that heating process occurs at constant pressure, the phenomenon is modelled by the use of the First Law of Thermodynamics:

q_{in} = h_{g} - h_{mix}

The specific enthalpies are:

Liquid-Vapor Mixture:

h_{mix} = 2217.2\,\frac{kJ}{kg}

Saturated Vapor:

h_{g} = 2745.8\,\frac{kJ}{kg}

The thermal energy per unit mass required to heat the steam is:

q_{in} = 2745.8\,\frac{kJ}{kg} - 2217.2\,\frac{kJ}{kg}

q_{in} = 528.6\,\frac{kJ}{kg}

A horizontal 20-mm diameter tube is to carry a laminar flow of SAE 30 oil. What pressure drop. (p1-p2) is needed to produce a fl
notsponge [240]

Answer:

P_1-P_2=795.18 Pa

Explanation:

Given that diameter of tube= 20 mm

flow rate = 72 lt/hr

The properties of SAE 30 oil at 30°C

\mu =155.31 mPa

\rho =872.5 \frac{kg}{m^3}

We know that volume flow rate Q= AV

2\times 10^{-5}=\dfrac{\pi}{4}\times{0.02^2}V

V= 0.064 m/s

Now lets find Reynolds number to check the type of flow

Re=\dfrac{\rho VD}{\mu }

Re=\dfrac{872.5\times 0.064\times0.020}{0.15531 }

Re=7.18 So we can say that this is laminar flow and we know that pressure drop for laminar flow is given as

P_1-P_2=\dfrac{32\mu VL}{d^2}

Now by putting the values the pressure drop for per unit length

P_1-P_2=\dfrac{32\times 0.15531\times 0.064 }{0.02^2}

P_1-P_2=795.18 Pa
