Q1 The crank of a slider mechanism rotates clockwise at a constant speed of 300 rpm. The crank is 15Q mm and the connecting rod is 60P mm long. Determine: a) Linear velocity and acceleration of the Slider. b) Angular velocity and angular acceleration of the connecting rod, at a crank angle of 45° from inner dead centre position.

Methane (CH4) enters a compressor operating at steady state with a mass flow rate of 170 lbm/hr. The methane enters the compressor at p1 = 15 lbf/in2 , T1 = 80F and exits at p2 = 100 lbf/in2 . The work input to the compressor is 15 hp. Assume ideal gas behavior for the methane with constant specific heats (cp = 0.538 Btu/lbm·R, cv = 0.414 Btu/lbm·R). Kinetic and potential energy effects are negligible and the compressor is insulated

1)Determine the temperature at the exit of the compressor, in F.

2) Determine the rate of entropy production, Btu/hr·R, in the compressor

electric current flows through an infinitely long hollow cylindrical copper bar having internal and external diameters of 15 mm and 25 mm respectively. The temperature on the bar internal and external surfaces are maintained constant. The bar carries a current density of 5.5 x 107 A/m2 and the internal surface temperature is maintained at 45oC with no heat loss from the external surface due to insulation. The copper bar has thermal conductivity of 380 W/m.K and electrical resistivity of 2.5 x 10-8Ωm.Assume that the temperature changes in the radial direction only and neglect the end effects in the bar.(a)Derive the temperature distribution equation in the radial direction.(b)Find the temperature on the insulated external surface of the copper bar. (c)Calculate the amount of heat flux through the internal surface per metre length of the bar.

You want to design a magnetic device to keep cupboard doors closed. What are the design consideration? Suggest suitable materials that may be used.

A fluidic storage tank has a square cross-section (3m x 3m) and a height of 10m. The tank is half-filled with a fluid with the density of 200kg/m3. The tank suddenly develops a leak. A sensor inside the tank instantaneously alerts the owner that the height of the fluid in the tank is decreasing by 1mm/min. Find the flow rate out of the tank at that moment in time.
