b) Ammonia at a pressure of 40 lbf/in.2 has a specific internal energy of 308.75 Btu/lb. Determine the specific volume at the state, in ft3/lb.

Real-world fluid flows can exhibit a combination of laminar and turbulent characteristics, depending on factors such as flow velocity, fluid properties, and the presence of obstacles or disturbances.

a) Liquid moves faster in a turbulent flow than in a laminar flow.

This statement is generally true. In a turbulent flow, the fluid moves in a chaotic manner, characterized by eddies and swirling motion. This turbulent motion enhances the mixing and transport of fluid particles, which can result in higher overall flow velocities compared to laminar flow, where fluid moves smoothly in parallel layers.

b) Turbulent flow produces more noise than laminar flow.

This statement is generally true. Turbulent flow is associated with fluctuating velocities and pressure fluctuations, which can generate noise. The irregular motion and collisions of fluid particles in turbulent flow create vibrations and sound waves, resulting in higher noise levels compared to the smooth, ordered flow of laminar flow.

c) Laminar flow does not change in time (it is a quasi-steady state), while turbulent flow is unsteady.

This statement is generally true. Laminar flow is characterized by smooth and ordered flow with parallel streamlines. It remains relatively constant over time, assuming steady conditions. On the other hand, turbulent flow is characterized by irregular and unsteady motion with constantly changing velocities and pressure fluctuations. Turbulent flow exhibits fluctuations in time and space due to the presence of eddies and vortices.

d) Streamlines of a laminar flow stick together, but diverge in a turbulent case.

This statement is generally true. In laminar flow function, adjacent fluid particles move smoothly and in parallel along the streamlines without significant mixing or cross-stream diffusion. As a result, the streamlines tend to remain close together and maintain their initial separation. In turbulent flow, however, the chaotic motion and mixing of fluid particles cause streamlines to diverge and become highly convoluted, leading to intermingling and spreading of fluid particles. Real-world fluid flows can exhibit a combination of laminar and turbulent characteristics, depending on factors such as flow velocity, fluid properties, and the presence of obstacles or disturbances.

Based on the provided options, the scientific expression that is the same as 1545.5347 is 154553.4e3. Therefore, the correct option is option D.

A scientific expression, often known as scientific notation, is a method of representing extremely big or extremely small integers. It is often used to simplify the representation of such numbers in scientific and mathematical operations. A number is expressed in scientific notation as a product of two parts: a coefficient and a power of ten.

The coefficient is a value between 1 and 10, and the power of 10 determines how far the decimal point should be moved. The "e3" signifies multiplying the integer by 10 raised to the power of 3, which is similar to moving the decimal point three places to the right in this formula. As a result, 154553.4e3 equals 154553.4103, which simplifies to 154553400.

Therefore, the correct option is option D.

Answer:

1. The thermal efficiency of the cycle is 57.913%

2. The heat input is 32165.68 kJ/kg

3. The work output is -18.628.11 kJ/kg

Explanation:

1. T₁ = 200C = 473.15 K

The thermal efficiency of the cycle is given by the relation;

\(\eta =\dfrac{k \beta ^{\gamma }-1}{\left [ \left ( k-1 \right ) \right + \gamma k(\beta -1)]r_{v}^{\gamma -1}}\)

Where:

k = Pressure ratio = p₃/p₂ = 1.3

γ = Specific heat ratio = 1.4

β = v₄/v₃

\(r_v\) = v₁/v₂

Which gives;

η = (1.3*(16/2)^1.4 - 1)/(((1.3 - 1) + 1.4*1.3*((16/2)-1))*16^0.4) = 0.57913

η = 57.913%

The thermal efficiency of the cycle = 57.913%

2. The heat input is given by the following relation;

Q = cv(T₂ - T₁) + cp(T₄ - T₃)

T₂/T₁ = (v₁/v₂)^(γ - 1) = 16^0.4 = 3.03

Therefore, T₂ = T₁×3.03= 473.15*3.03= 1434.323 K

T₃/T₂ = p₃/p₂ = 1.3

T₃ = T₂ ×1.3 = 1434.323 *1.3 = 1864.62 K

v₄/v₃ = T₄/T₃ = 16/2 = 8

T₄ = T₃×8 = 1864.62 × 8 = 14916.959 K

At 473.15 K, cv = 0.7386  cp = 1.026 kJ/(kg*K)

At 1434.323 K, cv = 0.9158 cp = 1.203

At 1864.62 K, cv = 0.9535 cp = 1.239

At 1864.62 K, cv = 0.874 cp = 1.24

Taking average values, we have

(0.7386   + 0.9158)/2= 0.8272 kJ/(kg*K)

cp = 1.24

The heat input is then found as follows;

Q = 0.874*(1434.323 - 473.15) + 2.4*(14916.96 - 1864.62) = 32165.68 kJ/kg

The heat input = 32165.68 kJ/kg

3. The work output is found as follows;

Given that η = -W/Q, we have;

-W = Q × η = 0.57913*32165.68 = -18.628.11 kJ/kg.

The work output = -18.628.11 kJ/kg.

Based on the calculations, the thermal efficiency for this dual cycle is 62.2%.

Given the following data:

Mathematically, the thermal efficiency for a dual cycle is given by this equation:

\(\eta= 1-\frac{1}{r^{k-1}} [\frac{r_pr_c^k -1}{kr_p(r_c-1)+r_p-1} ]\\\\\eta = 1-\frac{1}{16^{1.4-1}} [\frac{1.3(2)^{1.4} -1}{1.4(1.3)(2-1)+1.3-1}]\\\\\eta = 1-\frac{1}{16^{0.4}} [\frac{3.43 -1}{2.12}]\\\\\eta = 1-\frac{1}{3.03}\times [\frac{2.43}{2.12}]\\\\\eta =0.622\)

Thermal efficiency = 62.2%.

First of all, we would determine the temperatures as follows:

\(T_2 = T_1(\frac{V_1}{V_2} )^{k-1}\\\\T_2 = 473 \times (16 )^{1.4-1}\\\\T_2 = 473 \times (16 )^{0.4}\\\\T_2 = 1434\;K\)

\(T_3 = T_2(\frac{P_3}{P_2} )\\\\T_3 = 1434(1.3)\\\\T_3 = 1864\;K\)

\(T_4 = T_3(\frac{V_4}{V_3} )\\\\T_4 = 1864(2.0)\\\\T_4 = 3728\;K\)

Now, we can determine the heat input:

\(q_{in}=c_v(T_3-T_2)+c_p(T_4-T_3)\\\\q_{in}=0.717(1864-1434)+1.00(3728-1864)\\\\q_{in}=2172 \;kJ/kg.\)

In this problem, we are given the weight of soil in its natural state and after being dried, as well as the specific gravity of the soil. From this information, we can determine various properties such as degree of saturation, void ratio, porosity, and water content.

Additionally, we can calculate the volume of water required to saturate the soil in its natural state.

a) In the phase diagram, we have:

Wt (total weight) = 113 lbs

Ww (weight of water) = 113 - 96 = 17 lbs

Ws (weight of solids) = 96 lbs

Vt (total volume) = Vv (volume of voids) + Vs (volume of solids)

Vv is the volume of water, and Vs is the volume of solids.

We need additional information to determine the values of Vv and Vs.

b) To determine the degree of saturation (S), we use the equation:

S = (Ww / Ws) * 100

Substituting the given values, we can calculate the degree of saturation.

The void ratio (e) is the ratio of the volume of voids to the volume of solids. It can be calculated as:

e = Vv / Vs

The porosity (n) is the ratio of the volume of voids to the total volume. It can be calculated as:

n = Vv / Vt

The water content (ω) is the ratio of the weight of water to the weight of solids. It can be calculated as:

ω = (Ww / Ws) * 100

Using the given information, we can calculate the values of S, e, n, and ω.

c) The volume of water required to saturate 1 ft3 of soil in its natural state can be determined by multiplying the volume of voids (Vv) by the specific gravity (Gs) of the soil. Since the specific gravity is given as 2.70, we can calculate the volume of water required.

By applying the relevant equations and using the given information, we can determine the desired properties and volume of water required for the soil in its natural state.

Dry unit weight ( yd. ) :  yb / ( 1 + w )

For every set of data given

assuming  v = 1/30 ft^3

calculating for the 3 data set ( maximum dry density )

weight of soil (W) = 4.40

moisture content (%) (w) = 15.0 = 0.15

Bulk unit weight (yb) = 4.40 / (1/30)  = 132 Ib/ft^3
