1. Compute the temperature difference in Kelvin and in Rankine if the inside furnace temperature is
260°C and the outside temperature is -5°C.
2. Five objects in a region where the acceleration due to gravity is 30.2 ft/s² are as follows: x₁ = 400 g of
mass; x2 weighs 850g₁; X3 weighs 35 poundals; X4 weighs 31b₁; xs is 0.50 slug of mass. What is the total
mass expressed in lbm.
3. A ventilating fan of the bathroom of a building has a volume flow rate of 25 L/s and runs continuously.
If the density of air inside is 1.60 kg/m³, determine the mass of air vented out in 1 day.
4. Supposing two liquids of different densities p=1750 kg/m³ and p=500 kg/m³ were poured together
inside a 100L tank, filling it. If the resulting density of the mixture is 750 kg/m³, find (a) the mass and
volume of each liquids used, (b) the weight of the mixture if the local acceleration due to gravity is
g=9.81 m/s².
5. A cylindrical drum contains 50-ft of gasoline (SG=0.9), 20-ft of kerosene (SG = 0.8) and 30-ft of water.
If the top of the drum is exposed to the atmosphere, determine the pressure at the bottom of the
drum in kPa.
