A man having the mass of 73 kg sits in the chair which is pin-connected to the frame BC. If the man is always seated in an upright position, determine the magitudes of the horizontal and vertical reactions of the chair on the man at the instant . At this instant he has a speed of 6 m/s, which is increasing at 0.5 m/s^2.
calculate the enthalpy change of the universe during the process. Cp=Cv = 4.18 kj/kgK
Find flow rate A siphon made of a 1 in-inside-diameter pipe is used to maintain a constant level in a 20 ft-deep tank
If the final pressure is 1.0 MPa, determine (a) the temperature (°C) at the final state and (b) the heat transfer (kJ) during this process.
Steady State Thermal analysis can be use to simulate and obtain results to support the design optimization / objectives
determine the final temperature °R, and the final pressure in lbf/in^2. Rair = 53.33 ft·lbf/lb·°R. Assume ideal gas behavior and solve problem using.
Estimate the time necessary to achieve the same concentration at a 5.3-mm position for an identical steel and at the same carburizing temperature.
What load P allow can be supported at the midpoint of the bar if the yield stress in the steel wires is 220 MPa and in the aluminium wire is 80 MPa? A saftey factor of n = 2 is needed.
Calculating a Constant Pressure Process, In a constant pressure, nonflow process, 6Btus of heat are added to a gas while the volumes change from 1.6ft^3 to 2.0ft^3
The heat offusion of aluminum is 3.97 10^5 J/kg; the heat of fusion of mercury is 1.18 10^4. What is the effeciency of this engine?
Product and Engineering Design Review
Determine the COP of the heat pump that applies energy to a house at a rate of 4500kj/h for each kW of electric power it draws. Also, determine the rate of the energy absorption from the outdoor air.
Two kilograms of air within a piston-cylinder assembly execute a carnot power cycle with maximum and minimum temperatures of 750k and 300k, respectively.
