Heat from electricity VS Heat pump | Thermodynamics Part (1 of 2)

Welcome to Engineering Hack! In today's video we are solving a part 1 Thermodynamic's heat pump problem. The problem tells us that a Carnot heat pump is to be used to heat a house and maintain it at 25°C in winter, and we want to know how long the heat pump ran on that day, the total heating costs, assuming an average price of 0.11$/kWh for electricity and the heating cost for the same day if resistance heating is used instead of a heat pump. The problem requires you to know what is the Carnot heat pump and how to use it, and some other definitions, such as coefficient of performance. Everything else comes by analyzing the problem and the system at hand. Problem statement: A Carnot heat pump is to be used to heat a house and maintain it at 25°C in winter. On a day when the average outdoor temperature remains at about 2°C, the house is estimated to lose heat at a rate of 55,000kJ/h. If the heat pump consumes 4.8kW of power while operating, determine (a) how long the heat pump ran on that day; (b) the total heating costs, assuming an average price of 0.11$/kWh for electricity; and (c) the heating cost for the same day if resistance heating is used instead of a heat pump. Answer a) 5.895 h/day b) $3.11 for a full day c) $40.3 for a full day In this video: 00:00 Intro 00:23 Problem statement 01:16 Problem analysis 04:21 Part (a) ‘’how long the heat pump ran on that day’’ 🎓 Can you trust the answers and solutions provided? Well, you never should trust anything 100%. Make sure you are checking for yourself. When I’m solving the questions, I always solve on my own and then check the results against other sources. If there is divergence, I look for more sources. So while I can’t promise you everything will be 100% correct, I can promise I’ve done my due diligence before posting.
