Question

Air flows at 0.05 kg/s through n insulated circular duct such that the (gauge) pressure immediately downstream of a blower is 10 kPa You may neglect the impact of elevation change in your analysis. Part A the air that would be expected between upstream and downstream locations. If the pressure at a downstream location within the duct is measured as 8 kPa, estimate the change the temperature Express your answer to three significant figures Itvec ΑΣΦ ? AT= Request Answar Submit Part B If a blower was used to raise the pressure in the duct described in Part A by 2 kPa at a single location, estimate the power required to drive the blower if it has an efficiency of 94 % . Express your answer to three significant fiqures and include appropriate units. w Value Units Submit Request Answer Provide Feedback
