Answer:
Δu=1300kJ/kg
Explanation:
Energy at the initial state
Is saturated vapor at initial pressure we have
Process 2-3 is a constant volume process
The overall in internal energy
Δu=u₁-u₃
We replace the values in equation
Δu=u₁-u₃
Δu=1300kJ/kg
Answer:
Explanation:
Given
initially mass is stretched to
Let k be the spring Constant of spring
Therefore Total Mechanical Energy is
Position at which kinetic Energy is equal to Elastic Potential Energy
it is given
thus
