Hi,i want an 5 solved examples for (differential equation in fluid dynamics )
*the exampls (proplems) should be have ordinary differential equation in Operative of the question (It is preferable to be for the highest order)
and The answer should be a hand writing solution to these differential equations

The circumferential velocities in a free vertex and forced vortex, respectively, are u = C/r and u = wr, where the radius in meters, velocity is in m/s, and C is 8 m^2/s, and w = 2 rad/s. For both cases, calculate the circulation around a circular path with a radius of 1m and a center at (0,0). Are these inviscid flows? Note that ur = 0.

A test was conducted on a 4-stroke four cylinder engine having 6.9 cm diameter and 8.9 cm stroke. The fuel supply to the engine is 0.065 kg/min. The B.P measurements are given below with constant engine speed of 300 rpm: With all cylinder firing = 16.9 kW Cut off at 1st cylinder = 8.46 kW Cut off at 2nd cylinder = 8.56 kW Cut off at 3rd cylinder = 8.6 kW Cut off at 1st cylinder = 8.46 kW If clearance volume is 70 cm3 then find the mechanical efficiency, Indicate Power, Indicated thermal efficiency, Indicated mean effective pressure and also comment about the engine type whether it is SI or CI? Take Calorific value of fuel = 43500 kJ/kg

A substance contained in a flexible, well-insulated container undergoes an expansion process from an initial state with a specific volume of 10 ft3 /lb and pressure of 12 lbf/in2 to a final state with a specific volume of 24 ft3 /lb. During the process, the substance’s pressure varies according to Equation 1 where pi is the substance’s initial pressure and vi is the substance’s initial specific volume. The substance’s internal energy decreases by 500 Btu during the process. Neglect potential and kinetic energy changes.
a. Determine the specific work done on the substance in Btu/lb.
b. Determine the mass of the substance in lb.

A steam power plant operates on a regenerative Rankine cycle with two feedwater heaters, one closed and one open. Steam enters the turbine at 12.5 MPa and 550ºC and exhausts to the condenser at 10 kPa. Steam is extracted from the turbine at 1 MPa for the closed feedwater heater and 0.8 MPa for the open one. The feedwater is heated to the condensation temperature of the extracted steam in the closed feedwater heater. The extracted steam leaves the closed feedwater heater as a saturated liquid, which is subsequently throttled to the open feedwater heater. Show the cycle on a T-s diagram with respect to saturation lines, and determine(a) the mass flow rate of steam through the boiler for a net power output of 350 MW and (b) the thermal efficiency of the cycle.
