The velocity potential function is given by 𝜑 = 5 (x2 –y 2 ).Calculate the velocity components at the point (4, 5).

 For the MHC-PMS (Mental Health Care Patient Management System), propose a set of use cases that illustrates the interactions between a doctor, who sees patients and prescribes medicine and treatments, and the MHC-PMS.

A garden hose attached with a nozzle us used to fill a 15-gal bucket. The 

inner diameter of the hose is 4 cm, and it reduces to 1 cm at the nozzle 

exit. If it takes 1 minute to fill the bucket with water, determine (a) the 

volume and mass flow rates of water through the hose, and (b) the 

average velocity of water at the nozzle exit.

Two beams, A and B, made with the same materials are subjected to a three-point bending test, Beam A has a dimension of 2.5 in x 1.25 in x 0.5 in while Beam B has a dimension of 1.5 in x 1.5 in x 0.75in. compare the respective fracture loads that will cause the beams to fail

By referring to the figure below identify and discuss the factors that affect the adoption of new irrigation technologies. The discussion 

should be arranged as per the categories of factors in the conceptual framework (e.g. individual factors should all be discussed under 

the same sub-heading)

1. Individual factors

2. Economic factors

3. Environmental factors

4. Organization factors

5. Social factors
