A mixture of saturated liquid water and saturated steam at
T = 120 °C has a specific enthalpy of 2000 kJ⁄kg. What is
the quality of this mixture?
if you could show how to do it, that'd be great.

Saturated steam at 100 C is heated to 400 C. Use the steam table
to determine the required heat input if continuous stream flowing
at 150 kg/min undergoes this process at constant pressure.

A piston-cylinder device contains a saturated mixture of steam
and water having a total mass of 0.5 kg at a pressure of 160 kPa
and an initial volume of 100 liters. Heat is then added and the
fluid expands at constant pressure until it reaches a saturated
vapor state.
a) Draw a diagram representing the process showing the initial
and final states of the system.
b) Sketch this process on a P-v diagram with respect to the
saturation lines, critical...

Saturated steam at a gauge pressure of 0.50 bar is to be used to
heat a stream of ethane.
The ethane enters a heat exchanger at 16°C and 1.5 bar gauge
pressure at a rate of 795 m3/min and is heated at
constant pressure to 93°C.
The steam condenses and leaves the exchanger as a liquid at
20.0°C.
The specific enthalpy of ethane at the given pressure is 941 kJ/kg
at 16°C and 1073 kJ/kg at 93°C.

A bomb calorimeter, or constant volume calorimeter, is a device
often used to determine the heat of combustion of fuels and the
energy content of foods. Since the "bomb" itself can absorb energy,
a separate experiment is needed to determine the heat capacity of
the calorimeter. This is known as calibrating the calorimeter. In
the laboratory a student burns a 0.466-g sample of 1,8-octanediol
(C8H18O2) in a bomb calorimeter containing 1200. g of water. The
temperature increases from 25.90 °C...

1.A bomb calorimeter, or a constant volume calorimeter, is a
device often used to determine the heat of combustion of fuels and
the energy content of foods. In an experiment, a 0.3807 g sample of
1,6-hexanediol (C6H14O2) is burned completely in a bomb
calorimeter. The calorimeter is surrounded by 1.139×103 g of water.
During the combustion the temperature increases from 25.30 to 27.59
°C. The heat capacity of water is 4.184 J g-1°C-1. The heat
capacity of the calorimeter was...

In the laboratory a"coffee cup" calorimeter, or constant
pressure calorimeter, is frequently used to determine the specific
heat of a solid, or to measure the energy of a solution phase
reaction. A student heats65.62grams ofzincto98.24 °C and then drops
it into a cup containing75.87grams of water at23.87 °C. She
measures the final temperature to be29.24 °C. The heat capacity of
the calorimeter (sometimes referred to as thecalorimeter constant)
was determined in a separate experiment to be1.54J/°C. Assuming
that no heat...
