Students in a laboratory are studying air flowing at steady-state through a horizontal insulated duct. One student group reports the measured pressure, temperature, and velocity at one location in the duct as 0.95 bar, 67 °C, and 75 m/s, respectively. The group reports the following values at another location in the duct: 0.8 bar, 22 °C, and 310 m/s. The group neglected to note the direction of flow on the datasheet, however.
Using the data provided, determine the direction of flow.

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

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

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.
