Answer:
(a) Effectiveness of the regenerator= 0.433
(b) The rate of heat removal=21.38 kW
Explanation:
The solution and complete explanation for the above question and mentioned conditions is given below in the attached document.i hope my explanation will help you in understanding this particular question.
Density of cylinder = 11.4g/cm3
Volume of cylinder = h r2
but height (h) = 5.50cm
radius(r) = d/2 = 2.50/2 = 1.25cm
Hence Volume = 5.50 × (1.25)2
= 8.6cm3
Density = Mass/Volume
Hence Mass of the cylinder =
Density × Volume
Mass = 11.4 × 8.6 = 94.04g.
