Two streams of humid air are to be mixed to produce 600 cfm of air at 30°C and 30% relative humidity. If stream 1 is 200 cfm at 20°C and saturated, what is (a) the mass flow rate of stream 2, (b) the temperature (dry bulb) of stream 2, and (c) the relative humidity of stream 2? (25 points) Show the process on a psychrometric chart (5 points). The process takes place at sea level. Upload the chart with your solution.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
