please show me a sep wise solution for these problem as i am trying to learn from your solution. if you cant or you answer partially dont answer please. Problem 3 (20 pts): Consider a Carnot engine cycle in which we take an ideal monoatomic gas from point Ou a)on first leg ofthe cycle, a-+ b, we take the gas through an isothermal expansion at temperature TH Given the values shown on the P and V axes for the state...
please do 4, and 5 4. The open-circuit voltage of a battery is 12 volts and it's internal (i.e., source) resistance is one ohm. Using a load resistor as a heating element to extract maximal power from the battery to heat up a container of 1 cubic meter of water (to be used as a thermal reservoir for a steam engine). (a) How long (i.e., how many seconds) does it take to bring that water from 32 degrees Celsius to...
Tutorial Questions 1.1. Water is the working fluid in an ideal Rankine cycle. The condenser pressure is kPa, and saturated vapor enters the turbine at 10 MPa. Determine the heat transfer rates, in kJ per kg of steam flowing, for the working fluid passing through the boiler and condenser and calculate the thermal efficiency.2. Water is the working fluid in an ideal Rankine cycle. Saturated vapor enters the turbine at 16 MPa, and the condenser pressure is 8 kPa ....
We have seen that the Carnot cycle can be used to determine the maximum efficiency of a heat engine. The efficiency is defined as the sum of all of the work during the cycle divided by the amount of heat exchanged during the expansion process: efficiency=?1 +?2 +?3 +?3 /?1 Theoretically, the efficiency of the engine can be determined with the hot and cold temperature of the cycle. efficiency = ?h − ?c/ ?h In this problem, we will calculate...
Thermodynamics 1. Saturated liquid H20 at 16 MPa is fed into the boiler of a variant of a Carnot cycle (but simplified Rankin cycle) where the working fluid is not an ideal gas. Saturated H20 vapor is fed into the turbine of the same turbine. The condenser of this turbine is operated at 8 kPa. The mass flowrate of the H20 in this cycle is 7.2x103 kg/min. Draw the path of this process on T-s diagram. Estimate the thermal efficiency...

This heat is used in an engine that is connected to the sea water at T 20°C as low temperature reservoir. The engine has an efficiency of 51%. nuclear power plant generates (A) What is the electrical power output of this power plant? (The electrical enerzy output is equal to...
Problem 3 In modern high-speed compression ignition engines, fuel is injected into the combustion chamber much sooner than in early diesel engines. That means, heat is added partly at constant volume and partly at constant pressure. The advantage of this modification is that more time is available for the fuel to completely combust. The ideal dual cycle consists of the following operations: • Process -: Isentropic compression • Process -3: Addition of heat at constant volume. • Process - Addition...
