Steam enters a nozzle at 400°C and 700 kPa with a velocity of 10 m/s, and leaves at 320°C and 150 kPa while losing heat at a rate of 25 kW. For an inlet area of 800 cm2. Determine the volumetric flow rate of the steam in m3/s

An insulated pipe of inside diameter 50 mm contains steam of specific enthalpy2·794 MJ/kg and specific volume 0·0394 m3 /kg. The pipe then reduces to 25 mmdiameter, and the specific enthalpy is then 2·786 MJ /kg and the specific volume is0·1043 m/kg. Determine the mass flow rate of the steam and its velocity in bothsections of the pipe

Steam at 5 MPa and 400°C enters a nozzle steadily with avelocity of 80 m/s, and it leaves at 2 MPa and 300°C. Theinlet area of the nozzle is 50 cm², andthe heat is beinglost at a rate of 120 kJ/s. Determine (a) the mass flow rate of the steam, (b) the exit velocity of the steam, and (c) the exitarea of the nozzle.

An air cannon uses compressed air to propel a projectile from rest to a final velocity. Consider an air cannon that is to accelerate a 10-gram projectile to a speed of 300 m/s using compressed air, whose temperature cannot exceed 20°C. The volume of the storage tank is not to exceed 0.1 m3 . Select the storage volume size and maximum storage pressure that require the minimum amount of energy to fill the tank.
