Problem 2
Consider the power drawn by a resistance load in a DC circuit. The power is calculated as P = VI or P = 1²R. It is
given that the normalized uncertainty or % percentage uncertainty in measurements of I, R, and V are the same.
Find the uncertainty in P using the two different expressions for power. Is the uncertainty using the two methods
the same? If not, WHY, explain?

- I tried solving this one but I have no idea where I went wrong can you please help me out with this?arrow_forwardDuring a picnic on a hot summer day, all the cold drinks disappear quickly, and the only available drinks are those at the ambient temperature of 85°F. In an effort to cool a 12- fluid-oz drink in a can, a person grabs the can and starts shaking it in the iced water of the chest at 32°F. Using the properties of water for the drink, determine the mass of ice that will melt by the time the canned drink cools to 37°F. The density and specific heat of water at the average temperature of (85+37)/2 = 61ºF are ρ = 62.3 lbm/ft3 and cp = 1.0 Btu/lbmºF (Table A-3E). The heat of fusion of water is 143.5 Btu/lbm. The mass of ice that will melt by the time the canned drink cools to 37°F is lbm.arrow_forwardSteam enters a nozzle at 400°C and 800 kPa with a velocity of 10 m/s and leaves at 375°C and 400 kPa while losing heat at a rate of 26.5 kW. For an inlet area of 800 cm2, determine the velocity and the volume flow rate of the steam at the nozzle exit. Use steam tables.
