Answer:
Explanation:
Assuming statics
The average force is (60 + 0) / 2 = 30 N
E = Fd = 30(0.005) = 0.15 J
or
k = F/d = 60/0.005 = 12000 N/m
E = ½kx² = ½(12000)0.005² = 0.15 J
Answer:
Explanation:
Let establish a control volume in the industrial pressure cooker, which is a transient state system. From the First Law of Thermodynamics, the heating process is modelled:
The heat transfered to the cooker is:
Properties at each state are described below:
State 1
State 2
The heat transfered to the cooker is:
