Answer:
Isentropic compression in a pump, Constant heat addition in a boiler, Isentropic expansion in a turbine, constant heat rejection in a condenser
Explanation:
Ideal rankine cycle schematic diagram and T-S diagram is shown in below figure
The process 1-2 is isentropic compression is taking place in pump.
The process 2-3 is constant heat addition, heat addition takes places at boiler.
The process 3-4 is isentropic expansion, is taking place is turbine.
The process 4-1 is constant heat rejection , takes place in condenser.
Answer:
η = 0.5 = 50%
Explanation:
The efficiency of the power cycle is given by the following formula:
where,
where,
η = efficiency = ?
Q₁ = heat received from hot reservoir = 1000 KJ
Q₂ = heat discharged to cold reservoir = 500 KJ
Therefore,
<u>η = 0.5 = 50%</u>
Answer:
166.6 N
Explanation:
Given that,
Force, F₁ = 20 N
Area, A₁ = 10 dm² = 1000 cm²
We need to find the new force if the area of the larger piston is 120 cm². According to Pascal's law,
So, the force on the larger piston is equal to 166.7 N.
The ballpoint from a pen at a distance of about <u>4000</u> kilometers.
Alpha Centauri is the closest star device. Distance from Earth 4,365 al (forty 000 billion kilometers. The solar (yellow famous person) distance from Earth is 150 000 000 km, the exoplanet distance from Alpha Centauri b (orange famous person) 6 000 000 km.
Shifts in starlight from Proxima Centauri, found over extra than 2 years, screen its 1/3 planet. Astronomers have observed a 3rd planet orbiting Proxima Centauri, the star closest to the solar.
Proxima Centauri, the nearest megastar to our own, remains forty,208,000,000,000 km away. (Or about 268,770 AU.)

Answer:
Torque = -1799.52 Nm or 1799.52 Nm (clockwise direction)
Explanation:
Torque = Force x Perpendicular distance
Here force is given as 18.4 N and Perpendicular distance = 97.8 m
Substituting
Torque = Force x Perpendicular distance = 18.4 x 97.8 = 1799.52 Nm
Torque = 1799.52 Nm (clockwise direction)
Usually anticlockwise is positive
So torque = -1799.52 Nm
