Two air streams are mixed steadily and adiabatically. the first stream enters at 35 °C, and 30 percent relative humidity at a rate of 15 m^3/min, while the second stream enters at 12 °C, and 90 percent relative humidity at a rate of 25 m^3/min. Assuming that the mixing process occurs at a pressure of 1 atm.
Determine the quantities below:
(a) The specific humidity.
(b) The relative humidity.
(c) The dry-bulb temperature.
(d) The volume flow rate of the mixture.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation
