A ship driven by reaction jets and discharging astern is found to have resistance to motion of 3.5 km/hr. The velocity of jet relative to ship is 18 m/s. Find the number of jets if each has an area of 100 cm2. Also, calculate the propulsive efficiency and the power required to work the pump for the following cases: (a) Inlet orifices at right angles to ship motion (b) Inlet orifices face the direction of ship motion

The gas stream from a sulfur burner is composed of 15-mol-% SO2 20-mol-% O2 and 65 - mol -% N2. This gas stream at 1 bar and 753.15 K (480 ° C) enters a catalytic converter, where the SO2 is further oxidized to SO3. Assuming that the reaction reaches equilibrium, how much heat must be removed from the converter to maintain isothermal conditions? Base your answer on 1 mol of entering gas.

A perfect gas undergoes a cycle comprises of three processes. It is first compressed isothermally from 1 bar and 27°C to 1/8* of its initial volume. The energy is then added at constant pressure, increasing the temperature of gas and the cycle is completed by isentropic expansion to original conditions. Take Cp = 1.25 kJ/kgK and R = 0.5 kJ/kgK. Calculate the maximum cycle temperature and pressure. Also, find the net work transfer per kg.

A post-tensioned prestressed concrete T-beam with unbonded tendons is made up of a flange 300 mm wide and 150 mm thick and the width of the rib is 150 mm. The effective depth of the section is 320 mm. The beam is prestressed by 24 wires each of 5 mm diameter having a characteristic strength of 1650 N/mm2. The effective stress after all losses is 900 N/. If the cube strength of concrete is 56 N/, estimate the flexural strength of the section using provisions of (a) Indian (b) British
