CO2 is needed in a surgical suite for abdominal laparoscopic surgery. You have already designed a nozzle to step down the pressure from the gas cylinder to the delivery hose. The well-insulated delivery hose has a 2.2 mm inner diameter. The inlet conditions to the delivery hose are 103 psia and 17°C. Typically, the surgeon uses 4 to 6 L/min of gas at pressures between 10 to 20 mm Hg to inflate the peritoneal cavity; however, the delivery system must be able to provide flow rate of 17.5 L/min at 20.0 mm Hg for safety. The surgeon will use a pin valve to control the flow rate and maintain the operating space. The gas temperature should not be any colder than 10°C when delivered to patient, or tissue damage might occur. Determine the acceptable delivery hose length to meet the surgical criteria. State assumptions.
4. Air enters a circular conduit at a pressure of 105 kPaa and leaves at an outlet pressure of 108 kPaa. The outlet is at a higher level than the inlet with a difference of elevation of 15 m. The cross-sectional diameter at the inlet is 50 cm, while at the outlet is at 85 cm. Calculate the volume flow rate of air in CMH. Take the density of air as 1.2 kgm/m³
Fluid X56-1 (density = 1300 kg/m3; M = 253 kg/kmol) is pumped at a rate of 4.58 m3/hour from a storage tank to a processing unit. The pressure at the inlet to the processing unit is atmospheric while the air pressure in the storage tank is 1.25 atm. The storage tank contains fluid with a height of 1.8 m. The pump, located just outside the bottom of the tank, has a pressure at the exit point of 350 kPa. The pump is located 15 m lower than the processing unit. The pipe transporting the fluid is commercial steel with an inside diameter of 3 cm. Assume the viscosity is 42 mPa*s.a) What is the Reynold’s number for flow in the pipe?b) Is the flow laminar or turbulent?c) What is the pressure (kPa) at the inlet of the pump?d) What is the power (kW) supplied by the pump?e) Calculate the length (m) of the pipe.

Q.3 A steel bar at a temperature of 500°C is dropped into an insulated bath containing 20 kg water at 120°C. The temperature of water and Steel reaches steadily to 150°C. If specific heat for water is 4 .180 kJ/kg-K, calculate the change in entropy of system.
Give the significance of volume coefficient. The volume coefficient of expansions of water at 373 K is 7.8 x 10-4 K-1. Calculate the change in entropy when the pressure is increased from 1 bar to 100 bar. At 373 K, density of water is 958 kg/m3 .
1) In a mixing chamber, a 7kg/s water flow at 800kPa and 500°C (flow 1) is mixed with 3kg/s water flow at 800kPa and x=0 (saturated liquid) (flow 2). Determine quality (x) of the mixed flow (flow 3).
Solve the problem. An air compressor (an open system) receives 272 kg per min of air at 99.29 kPa and a specific volume of 0.026 m3/kg. The air flows steadiy through the compressor and is discharged at 689.5 kPa and 0.0051 m3/kg. The initial internal energy of the air is 1594 J/kg; at discharge, the internal energy is 6241 J/kg. The cooling water circulated around the cylinder carries away 4383 J/kg of air. The change in kinetic energy is 896 J/kg increase. Sketch an energy diagram. Compute the work.
An adiabatic turbine running on an ideal gas (R = 2.079 kJ/kg K, k = 5/3) has at the entrance 35 m/s and 530 °C. At the outlet the conditions are 90 m/s and 310 °C. Calculate the power that would produce a consumption of 150 g/s of gas. Thankyou :
