A heat pump operates at steady state maintains a house at 22 0C when the outside is -22 0C using 15 kW of power. The manufacturer claims that the power input required is 3.2 kW. Applying energy and entropy rate balances evaluate the claim.
an isolated system consists of a closed copper vessel of mass 0.1 kg containing 1 kg of liquid water each initially at
A composite wall consists of a 1 mm-thick stainless steel plate (AISI 316), 2 cm of plywood, and 2 cm of low-density particle board. The stainless steel surface is maintained at 380 K while the other side loses heat to ambient air at 300 K, with conv..
0.78 kg of helium fills a piston-cylinder device (initial volume of 0.5 m3 which is maintained at an absolute pressure of 240 kPa. Heat is added until the volume doubles. What is the temperature of the helium at the end of the process?
A hydraulic lift must lift 7000 lbs using oil that is under pressure of 130 lbs/in^2. what must be the surface area of the lift cylinder?
Determine the natural frequencies of the system. For the baseline system I get natural frequencies at the following engine speeds: 435, 2026, 2818, 5225, 7093, 10245, and 12153 rpm.
