(laminar flow) asphalt at 120°f, considered to be a newtonian fluid with a viscosity 67,000 times that of water and a specific gravity of 1.93, flows through a pipe of diameter 2.00 in. if the pressure gradient is 1.45 psi/ft, determine the flowrate assuming the pipe is (a) horizontal ft/s (b) vertical with flow up ft/s

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.

Consider two concentric spheres forming an enclosure with diameters of 12 cm and 18 cm the spheres are maintained at uniform temperatures ti-50°c and t2 = 250°c and have emissivities .45 and .8, respectively. determine the net rate of radiation heat transfer between the two spheres per unit surface area.
