CALIBRATION OF ORIFICEMETER

 

AIM: To determine the co-efficient of discharge Cd of Orifice meter

 

EQUIPMENTS AND COMPONENTS:

Orifice filled with a pipe of known diameter, manometer, collecting tank, stop watch.

 

THEORY:

            Orifice is a simple device to measure the flow in a pipe by reducing the flow passage in one section. The pressure difference is created between two sections. The measurement of pressure difference between two sections determine Cd of the Orifice.

            Since the diameter at passage of Orifice is less than that of pipe as the time reaches maximum value the pressure becomes less or pressure tap is provided at this section another pressure tap is provided at a distance of 0.9 to 1.1 times the diameter of pipe from Orifice plate where the pressure is maximum. From the collecting tank we can measure the actual discharge using the formulae.

PROCEDURE:

1.      Diameter of pipe and Orifice are noted down

2.      Air in the manometer pipe is removed by allowing it to pass through the pipe.

3.      The inlet and outlet values are brought to required position.

4.      For a constant discharge the readings of manometer are noted down.

5.      The above procedure is repeated for difference values of discharge.

6.      The graph of Qact v/s H is plotted, value of Cd is calculated

MINOR DISORDERS OF NEW BORN AND ITS MANAGEMENT - NURSING ASSIGNMENT

-
INTRODUCTION         Neonatal health problems are frequently found ranging from minor physical or physiological peculiarities to the serious life threatening illnesses. Minor problems should not be ignored lightly without adequate assessment of the conditions. Early diagnosis and management of the serious problems help to overcome life long disability and to reduce neonatal morbidity and mortality. Nurses are responsible to manage the minor problems and to detect the serious problems for early and prompt management along with appropriate nursing interventions and support to the mother. MINOR DISORDERS OF NEW BORN 1. VOMITING         Vomiting is one of the common manifestations in the neonates. Regurgitation after feeds should not be confused with vomiting. Mucus vomiting often hinged with blood is quite common soon after birth. It is due to irritation often gastric mucosa by the swallowed materials during birth. Causes: ·         Dietic ·         Over feeding

KANGAROO CARE - NURSING ASSIGNMENT

-
INTRODUCTION         Caring low birth weight baby is a great challenge for the neonatal care unit and the family. Number of low birth weighs baby is still for beyond the expected target in our country. The cost of the quality management of these babies is increasing day by day. Kangaroo care is low cost approach for the care of low birth weight baby. This method of care was introduced and popularized by Dr.Edger Ray, Dr.Martinez and Dr.Charpak in late 1970s. DEFINITION         Kangaroo Mother Care (KMC) is a special way of caring low birth weight infants by skin to skin contact if promotes their health and welling by effective thermal control, breast feeding and bonding. KMC is initiated in hospital and continued at home. COMPONENTS OF KMC         In KMC, the infant is continuously kept in skin contact by the mother and breastfed exclusively to the utmost extent.         The two components of KMC are; 1.    Skin to skin contact is provi
