20 ℃ Liquid water is flowing into a chamber with a mass flow rate of 1.5 kg/s and heated by mixing it with a superheated steam at 300 ℃. For a specified mixing temperature at 60 ℃, what is the mass flow rate of the steam we need to set and what is the mass flow rate of the 60 ℃ water we can get? Assume: • Mass flow rate ?̇ is the mass change per unit time, with the...
question 1) if 520.0 J are added to 150g of water at 30C, what will be the final temperature of water? question 2) if 520.0 J are removed to 150g of water at 30C, what will be the final temperature of water? ... I tried doing question 1 but I didnt understand how come the answer of the change of temperature of 0.8280 was changed to 8.3 C and then added with 30.0 to get the answer final temperature of...

Calculate the amount of water that must be fed into an heat exchanger that cools 100 kg/h of tomato sauce from 90 to 20°C. The tomato sauce contains 40% solids. The temperature of the water leaving the heat exchanger must not exceed the entering water temperature by 10°C. mw = 531.82 kg/h
Tutorial Questions 1.1. Water is the working fluid in an ideal Rankine cycle. The condenser pressure is kPa, and saturated vapor enters the turbine at 10 MPa. Determine the heat transfer rates, in kJ per kg of steam flowing, for the working fluid passing through the boiler and condenser and calculate the thermal efficiency.2. Water is the working fluid in an ideal Rankine cycle. Saturated vapor enters the turbine at 16 MPa, and the condenser pressure is 8 kPa ....
Calculate the amount of heat (in loules) that must be added to 50.0 g of water to increase the temperature from 26.3C to 52.70. The specific heat of water is 4.18 J/g C An 50.0 g iron nail was heated in a blacksmith forge until it glowed cherry red. It was then dropped into a calorimeter containing 50.0 g of water at room temperature (21.5°C) and swirled gently until the temperature reached its maximum. The final temperature was 26.0 C....
