Consider a closed rectangular chamber of dimensions 1 m x 1 m x 2.5 m with a circular lid on it of diameter, 2 cm. the air inside the chamber is at standard atmospheric conditions (pressure, p=1 atm, and temperature, t=25 c). (a) what is the mass of air inside the chamber (in kg)? then the chamber is heated to 2707 c. (b) what is the density inside the chamber (provided the lid remain closed)? (c) what is the pressure inside the change (in atm)? (d) what is the force applied on the lid by the trapped heated air (in n)?

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.

Give heat transfer applications for the following, (i) gas turbines (propulsion) ) gas turbines (power generation). (iii) steam turbines. (iv) combined heat and power (chp). (v) automotive engines
