Explain the difference between claperyon equation and Clausius claperyon equation

A gas turbine operates on a pressure ratio of 6. The inlet air temperature to the compressor

is 300 K and the temperature of air entering to the turbine is 580°C. If the volume rate of

air entering the compressor is 250 m3

/s. Calculate the net power output of the cycle. Also,

calculate the efficiency.

A heat pump working on the Carnot cycle takes in heat from a reservoir at 5°C and delivers

heat to a reservoir at 60°C. The heat pump is driven by a reversible heat engine which takes

in heat from a reservoir at 840°C and rejects heat to a reservoir at 60°C. The reversible heat

engine also forgives a machine that absorbs 30 kW. If the heat pump extract 17 kJ/s from

the 5°C reservoir, determine :

a) The rate of heat supply from the 840°C source

b) The rate of heat rejection to the 60°C sink.

A blower handles 1kg/s of air at 20^(@)C and consumes a power of 15kW.The inlet and outlet velocities of air are 100m/s and 150m/s respectively.Find the exit air temperature assuming adiabatic conditions.Take c_(p) of air is 1.005kJ/kg-K.

A 1-kg metal sample is heated to 90°C and then dropped into an insulated container containing 200 mL of water at 25°C. When thermal equilibrium is reached, the temperature of water rose to 40°C. What is the final temperature of the metal sample?

Finn and Jake saw a carousel-a horizontal rotating platform- with radiuse when they decided to ride with it. As they accelerate, the movement of the carousel is at constant speed unit it has reached an angular velocity after 2 complete revolutions. What is the angular acceleration of the carousel during this time?

The volume of a gas increases from 3Litres to 9Litres at a constant pressure of 4atm. Next,heat is added to increase the pressure to 10atm at constant finally heat is removed to decrease the pressure and volume back to the original values in a straight line path.

(a) Draw a PV-diagram

(b) Calculate the total workdone in this process.

Leave your answer in joules

What is the maximum wavelength of light that will cause photo electrons to be emitted

from sodium? What will the maximum kinetic energy of the photo electrons be if 200-nm

light falls on a sodium surface?

A gas is filled with oxygen at a temperature of 2atm. If the temperature is increased to 50°c and the pressure is increased to 5atm,by what factor does the density of the oxygen increases by

An ungranulated thermometer reads 2.0 and 12.9at ice andsteam point respectively.calculate the true temperature in kelvin when the thermometer reads 5.0
