Salsk061 [2.6K]4 years ago
8 0

Answer  and Explanation:

The two principles or corollaries of Carnot Theorem are listed below:

1). The efficiencies of all the reversible heat engines between any two thermal reservoirs working between the same temperatures will be equal to each other.

2). For every Carnot engine working between any two thermal reservoirs will have the same efficiency independent of the operating conditions and the nature of working substance. It only depends on the temperature of the thermal energy reservoirs.

When a technician is ohming out a load in a circuit, what reading should the technician get if the load is good
xz_007 [3.2K]

When a technician is ohming out a load in a circuit, the reading that the technician should get if the load is good is some numbers.

<h3>What does Ohming out a circuit mean?</h3>

The term “Ohming out a motor” is known to be the act of measuring the electrical resistance that is present in the motor windings and comparing it with the normal values.

Note that When a technician is ohming out a load in a circuit, the reading that the technician should get if the load is good is some numbers as it will tell if there is a measure of comparison or not.

Temka [501]

Answer:

Explanation:

Find the temperature at exit of compressor

T_2=300 \times 8^{\frac{1.667-1}{1.667} }\\=689.3k

Find the work done by the compressor

\frac{W}{m} =c_p(T_2-T_1)\\\\=5.19(689.3-300)\\=2020.4kJ/kg

Find the actual workdone by the compressor

\frac{W}{m} =n_c(\frac{W}{m} )\\\\=1 \times 2020.4kJ/kg

Find the temperature at exit of the turbine

T_4=\frac{1800}{8^{\frac{1.667-1}{1.667} }} \\\\=787.3k

Find the actual workdone by the turbine

1 \times 5.19 (1800-783.3)\\=5276.6kJ/kg

Find the temperature of the regeneration

\epsilon = \frac{T_5-T_2}{T_4-T_2} \\\\0.75=\frac{T_5-689.3}{783.3-689.3} \\\\T_5=759.8k

Find the heat supplied

Q_i_n=c_p(T_3-T_5)\\\\=5.19(1800-759.8)\\\\=5388.2kJ/kg

Find the thermal efficiency

n_t_h=\frac{W_t-W_c}{Q_i_n} \\\\=\frac{5276.6-2020.4}{5388.2} \\\\n_t_h=60.4

60.4%

Find the mass flow rate

m=\frac{W_net}{P} \\\\\frac{60 \times 10^3}{5276.6-2020.4} \\\\=18.42

Find the actual workdone by the compressor

\frac{W_c}{m} =\frac{(\frac{W}{m} )}{n_c} \\\\=\frac{2020.4}{0.8} \\\\=2525.5kg

Find the actual workdone by the turbine

\frac{W_t}{m} =n_t(\frac{W}{m} )\\\\=0.8 \times5.19(1800-783.3)\\\\=4221.2kJ/kg

Find the temperature of the compressor exit

\frac{W_t}{m} =c_p(T_2_a-T_1)\\2525.5=5.18(T_2_a-300)\\T_2_a=787.5k

Find the temperature at the turbine exit

4221.2=5.18(1800-T_4_a)\\\\T_4_a=985k

Find the temperature of regeneration

\epsilon =\frac{T_5-T_2}{T_4-T_2}\\\\0.75=\frac{T_5-787.5}{985-787.5}\\\\T_5=935.5k
