The aircraft A with radar detection equipment is flying horizontally at an altitude of 12.2 km and is increasing its speed at the rate of 1.76 m/s each second. Its radar locks onto an aircraft B flying in the same direction and in the same vertical plane at an altitude of 15.3 km. If A has a speed of 1110 km/h at the instant when = 23°, determine the values of and at this same instant if B has a constant speed of 1670 km/h.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

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.
