1. A certain nozzle expands a gas under isentropic conditions. nozzle entry velocity equals 90 m/sec, its final velocity 1500 the change in enthalpy of the gas? What percentage of error the initial velocity is neglected?
2. A rocket engine has following data: Propellant flow rate = 5.1 kg / s Nozzle exit diameter = 11 cm Nozzle exit pressure = 1.03 bar Ambient pressure = 1.013 bar Thrust chamber pressure = 20 bar Thrust = 6.8 kN. Find the follOWTing: Q) Exit Mach number (ii) Nozzle area ratio (iii)Throat area iv Pro weight flow coefficient (v) Characteristic velocity. Take specific heat ratio as 1.3.1
Its chamber or m/sec. What is is introduced if
The Reflective Portfolio is a means to review what you have learnt on a weekly basis, how concepts have related to your past experiences, how concepts could be applied to enhance your performance as a hotel leader, challenges and areas of confusion and other thoughts / opinions relating to your weekly learning experience. It is also recommended the unit learning outcomes are reflected upon for each entry.The Portfolio can be presented as a weekly / topic journal, for example:Introduction to Front OfficeExecutive HousekeepingEffective Inter-departmental CommunicationPreparation and Review of Night AuditSafety and SecurityLabour Cost and StaffingFacilities Management What is your outcome and how can you summarise your learning in relation to this outcome For example: In response to Week 2 Introduction to Front Office, the author has learnt of a number of issues related to hotel service delivery, including but not limited to the value of employee motivation.
