Consider the mixing of 0.8 kg/s of hot water at 348 k and 1 kg/s of cool water at 298 k that is generating warm water. assume no work is being done and the system is in steady state, but heat is lost at the rate of 30 kj/s during this mixing. find the temperature of the warm water flow stream? assume cp =4.18 kjkg

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m

Find the kinematic pressure of 160kpa. for air, r-287 j/ kg k. and hair al viscosity of air at a temperature of 50°c and an absolute (10 points) (b) find the dynamic viscosity of air at 110 °c. sutherland constant for air is 111k
