Water is the working fluid in a carnot vapor power cycle. saturated liquid enters the boiler at a pressure of 160 bar, and saturated vapor enters the turbine. the condenser pressure is 0.08 bar. determine
(a) the thermal efficiency.
(b) the back work ratio.
(c) the heat transfer to the working fluid per unit mass passing through boiler, in kj/kg.
(d) the heat transfer from the working fluid per unit mass passing through the condenser, in kj/kg.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.

the atomic mass is the bottom number on the element.

a) the particles of the chair are strongly held together.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
