Nitrogen gas enters a 0.450 m diameter pipe at 30.0 °C, 2.60 atm (absolute), and 6.30 m/s. The pipe rises 24.0 ft and then falls 99.0 ft. The nitrogen gas exits the pipe at 30.0 °C and 1.10 atm (absolute).

Fluid Mechanics Quiz 5 Q1: Air at 200 °F and 60 psia flows in a 4-in.-diameter pipe at a rate of 0.52 lb/s. Determine the pressure at the 2-in.-diameter throat of a Venturi meter placed in the pipe. Q2: Water flows through a 40-mm-diameter nozzle meter in a 75-mm-diameter pipe at a rate of 0.015 m/s. Determine the pressure difference across the nozzle if the temperature is (3) 10 °C. or (b) 80 °c. Q3: Water flows through the orifice meter shown in Fig. below at a rate of 0. 10 cfs. If d = 0.1 ft, determine the value of h. Q- 2 in.

Saturated liquid ammonia is entering a 50 cm diameter 10-m long pipe at a steady 0.1 kg/s mass flow rate and a mean temperature of 0°C. It is exiting the pipe as saturated vapor at a mean temperature of 0°C. (a) What is the Reynolds number and flow regime at the beginning and at the end of the pipe? (b) If the surface temperature of the pipe can be assumed to be constant at 15°C in this section, what is the average convection coefficient of the ammonia flow? (a) 1343; 27075 (b) 553.6 W/m2K

An air pipe carries cool air at an inlet bulk temperature of 15C and a velocity of 12 m/s. The pipe is made of carbon steel of 0.25 m diameter, it is not insulated, and it( the pipe) will be maintained at temperature of 120C in order to raise the flowing air temperature to 45C. Calculate the Reynolds number, the heat transfer coefficient in W/(m^2K) and the lenght of this pipe in meters. Use Table A.4 to read the air properties.
