0.10865 killograms
Step-by-step explanation:
calculating the liquid mass of ammonia removed through the bottom value from a rigid tank at constant temperature.
Given:
temperature:
quality : 50% = 0.5
initial mass:
to find the removed liquid mass first we have to find total volume from which we can find remaining mass. as the tang is rigid the temperature and volume remains constant.
by taking the difference of mass we can determine the mass of liquid removed.
we have two phases at temperature with specific volume for liquid
and specific volume for vapor is
.
The Volume in the initial state is given by, (Using definition of specific volume)
using
substituting ,
,
we get
finally
we know the formula to find liquid mass is
density of ammonia is
inserting the values into the formula we get the value for liquid mass removed through the valve.
the final answer is
Answer:
Step-by-step explanation:
you have a right triangle
to find the missing length(x) you will use
a^2+b^2=c^2
where c is the hypotenuse
49^2=25^2+x
x^2=49^2-25^2=2401-625=1776
x==42.1
