Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

9. A pressure relief valve contains a poppet with a 0.65 – in² area on which system pressure acts. During assembly, a spring with a spring constant of 2000lb/in is installed in the valve to hold the poppet against its seat. The adjustment mechanism is then set so that the spring initially compresses 0.15in from its free-length condition. In order to pass full pump flow through the valve the PRV pressure setting, the poppet must move 0.10in from its fully closed position. Determine the (a) Cracking pressure (b) Full pump flow pressure (PRV pressure setting)
Please no written by hand solutions A 4-ton heat pump is installed. Desired flow rate is 12 USgpm. The runner and header from the Mechanical room is 110 feet in delivery and 110 feet in return. The fluid running in the system is Methanol-20%. The ground loop consists of three parallel vertical loops each 290 feet in length. The ground loop is made of 0.75" HDPE SDR 11 pipes and the runner-header is made of 1.25" HDPE SDR 11 pipes. The heatpump pressure drop is given 5.8 ft of wc for a flow of 6 gpm of water (Correction factor 20% Propylene Glycol:1.36, 20% Methanol: 1.25, 25% Ethanol: 1.32).

1. A building exhaust fan for a large commercial bullding weighs 180 pounds and operates at a speed of 600 rpm. Due to manufacturing tolerances, it may have a rotating imbalance. It is desired to limit force transmissibility to 2.5 as the fan passes through resonance during startup and wind-down. In addition, an Isolation of 90% is required at the operating speed of the fan. The fan's framework will be supported from the floor at 4 corners. Design, select, and specify vibration isolators at the four corners. It is acceptable to assume the center of gravity is symmetrical with respect to all four corners, enabling you to treat this as a single DOF system without pitch or yaw.
