Aperson makes iced tea by adding ice to 1.8 kg of hot tea, initially at 80°c. how many kilograms of ice, initially at 0°c, are required to bring the mixture to 10°c? the specific heat of water (and tea) is 4186 j/kg ∙ k, and the latent heat of fusion of ice is 3.34 × 105 j/kg.

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.

If vx = 7.00 units and vy = -7.60 units, determine the magnitude of v⃗ . determine the direction of v⃗ .
