Answer:
D) 7500 N/m
Explanation:
Given :
Work done by the spring, W = 6 J
Stretch in the spring, x = 4 cm = 0.04 m
Consider k be the spring constant.
The relation between work done and stretch of the spring is:
Substitute the suitable values in the above equation.
k = 7500 N/m
Answer:
mass flow rate at water condenses is 36.72 kg/min
Explanation:
given data
temperature t1 = 38°C
temperature t2 = 14°C
humidity ∅= 97 % = 0.97
rate v = 510 m³/min
to find out
mass flow rate at water condenses
solution
by gas equation we find here mass flow rate that is
pv = mRT
put here value and p is 0.066626 bar at 38°C and find m
m = 0.06626 × × 510 / 287×311
m = 37.85 kg/min
so at water condenses mass flow rate is express as
∅ = M / m
Mass flow rate M = ∅ × m
M = 0.97 × 37.85
mass flow rate = 36.72 kg/min
so mass flow rate at water condenses is 36.72 kg/min
