What are the basic operating conditions (temperature, maximum and minimum operating pressures), the basic physical conditions (specification of piping material, pipe diameters) and the MAWP for a simplified industrial oxygen piping system (hypothetical or based on a real example) that contains at least two branches with different diameters from the main branch.

A thermocouple junction is in the form of 8 mm diameter sphere. Properties of materialare: Cp = 420 J/kg-K; ρ = 8000 kg/m3 ; k = 40 W/m-K; h = 40 W/m2 -K. This junction isinitially at 40 oC and inserted in a stream of hot air at 300 oC. Find the following:a. Time constant of the thermocouple.b. The thermocouple is taken out from the hot air after 10 seconds and kept in still airat 30 oC. Assuming the heat transfer coefficient in air is 10 W/m2-oC, find thetemperature attained by the junction 20 seconds after removal from hot air.

KNOWN: Variation of local heat transfer coefficient with .x. Length of plate. FIND: Ratio of heat transfer coefficients for flow oriented in short and long directions. SCHEMATIC: Thermal boundary layer, hx=Cx, where C is a constant L 1 m or 0.75 m- ASSUMPTIONS: (1) Steady-state conditions, (2) Laminar flow, (3) Incompressible flow.

Question in image. i need help with q 2

Example(1-13): steam and water flow through 75 mm inside diameter pipe at flow rate of 0.05 and 1.5 m³/s respectivily. If the mean temperature and pressure are 330 K and 120 kpa, what is the pressure drop per unit length of pipe. Where the pipe roughness 0.00015 mm, liquid and gas viscosities are 0.52x10³ pa.s and 0.0133x10-³ pa.s.

Please show all steps, not Ai generated, has been wrong before. I need to understand the process.

A saturated steam at 410K is being transported in a pipeline (brass drawing tubing) at a rate of 1 grams/second. Pipe has inside diameter of 0.025 m . The tube is 100m long. The pressure at the entrance is 80kPa. What is the % of pressure drop? (use Perry's Handbook for the properties and constants) R = 8314J/kgmol.K; MW=18.02g/mol

Hand written plz otherwise skip... I'll rate plz asap

can you please work it all please please

i need the answer quickly
