Question: 1 kg of air in an insulated rigid tank of volume 1 m'is churned with a friction-less fan (see figure below) of 600 W capacity for 10 minutes. The fan efficiency is 100 %. Treating air as an ideal gas and neglecting kinetic and potential energy changes, what is the increase of pressure, to the nearest kPa? 600 W

Question: A well-insulated rigid hot water tank receives steady flow of water from two sources as shown in the figure below 1 kg/ s at 80 C 5 kgl s at 50 C Back-up heater at 60 C There is no accumulation of water in the tank. A back-up heater is provided to ensure a constant outflow temperature of water at 60 C from the tank under steady state. What is the required capacity of the back-up heater to the nearest kW?_
